Neutralization reactions are an essential part of chemistry, as they involve the combination of an acid and a base to form a salt and water. One such reaction is the neutralization of sulfuric acid (H2SO4) by sodium hydroxide (NaOH) in an aqueous solution. Let’s explore the reaction equation and products, as well as the explanation of the neutralization process.
Reaction Equation and Products
The reaction equation for the neutralization of sulfuric acid by sodium hydroxide can be represented as follows:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
In this equation, sulfuric acid (H2SO4) reacts with sodium hydroxide (NaOH) to produce sodium sulfate (Na2SO4) and water (H2O). The balanced equation shows that two moles of sodium hydroxide are required to neutralize one mole of sulfuric acid.
Explanation of Neutralization Process
The neutralization process occurs due to the transfer of protons (H+) from the acid to the hydroxide ions (OH-) from the base. In the case of sulfuric acid and sodium hydroxide, sulfuric acid donates two protons, while sodium hydroxide contributes two hydroxide ions.
When sulfuric acid is dissolved in water, it dissociates into hydrogen ions (H+) and sulfate ions (SO4^2-). Similarly, sodium hydroxide dissociates into sodium ions (Na+) and hydroxide ions (OH-) in aqueous solution.
During the neutralization reaction, the hydrogen ions from sulfuric acid combine with the hydroxide ions from sodium hydroxide to form water. The remaining ions, sodium and sulfate, combine to form sodium sulfate, which remains in solution.
The neutralization process can be understood in terms of the Arrhenius theory of acids and bases. According to this theory, an acid is a substance that donates hydrogen ions (H+), while a base is a substance that donates hydroxide ions (OH-). In the case of sulfuric acid and sodium hydroxide, the acid donates protons, and the base donates hydroxide ions, resulting in the formation of water and a salt.
It is important to note that sulfuric acid is a strong acid, meaning it completely dissociates in water, while sodium hydroxide is a strong base, fully ionizing in aqueous solution. This complete ionization allows for a complete neutralization reaction to occur.

The molecular formula of Al(H2O)6Br3 indicates that it contains one aluminum ion, six water molecules, and three bromide ions. The aluminum ion has an oxidation state of +3, which means it has lost three electrons to achieve a stable configuration.
In Al(H2O)6Br3, the aluminum ion acts as a Lewis acid, which is a substance that can accept a pair of electrons. The water molecules surrounding the aluminum ion act as ligands, providing a lone pair of electrons to form coordinate bonds with the aluminum ion. The bromide ions, on the other hand, act as counterions to balance the charge of the compound.
Explanation of its Acidic Properties
Al(H2O)6Br3 exhibits acidic properties when dissolved in water. When the compound is dissolved in water, the water molecules surrounding the aluminum ion can undergo a process called hydrolysis. Hydrolysis is a chemical reaction in which a compound reacts with water to produce ions.
In the case of Al(H2O)6Br3, the hydrolysis of the water molecules results in the formation of hydronium ions (H3O+) and hydroxide ions (OH-). The aluminum ion acts as a Lewis acid by accepting a pair of electrons from a water molecule, forming a coordinate bond. This process leads to the release of a hydrogen ion (H+), which combines with a water molecule to form a hydronium ion.
The hydrolysis reaction can be represented as follows:
[Al(H2O)6]3+ + H2O ⇌ [Al(H2O)5OH]2+ + H3O+
The formation of hydronium ions in the solution increases its acidity. The concentration of hydronium ions determines the pH of the solution. A higher concentration of hydronium ions corresponds to a lower pH, indicating a more acidic solution.
Amphoteric Nature of H2O
Water (H2O) is a fascinating molecule that exhibits an amphoteric nature, meaning it can act as both an acid and a base. This unique property is crucial for many chemical reactions and plays a significant role in various biological processes.

Addition of H3O+ to the Equilibrium
Effect of H3O+ on the equilibrium of the reaction
When H3O+ is added to the equilibrium of the h2so3 albr3 reaction, it has a significant impact on the equilibrium position. The addition of H3O+ can shift the equilibrium towards the formation of sulfurous acid (H2SO3) or aluminum bromide (AlBr3), depending on the conditions.
In an acidic solution, H3O+ acts as a Lewis acid, which can react with the Lewis base, AlBr3, to form a complex ion. This reaction can be represented as follows:
H3O+ + AlBr3 → [AlBr3(H2O)]+
The formation of the complex ion reduces the concentration of AlBr3 in the solution, thereby shifting the equilibrium towards the formation of H2SO3. This shift occurs because the reaction consumes AlBr3, leading to a decrease in its concentration and a subsequent increase in the concentration of H2SO3.
On the other hand, in a basic solution, H3O+ can react with H2SO3 to form hydrosulfite ions (HSO3-). This reaction can be represented as follows:
H3O+ + H2SO3 → HSO3- + H2O
The formation of hydrosulfite ions reduces the concentration of H2SO3 in the solution, thereby shifting the equilibrium towards the formation of AlBr3. This shift occurs because the reaction consumes H2SO3, leading to a decrease in its concentration and a subsequent increase in the concentration of AlBr3.
Explanation of the shift in equilibrium position
The shift in the equilibrium position can be explained by Le Chatelier’s principle, which states that when a system at equilibrium is subjected to a change in conditions, the system will adjust to counteract the change and restore equilibrium.
In the case of the h2so3 albr3 reaction, the addition of H3O+ disrupts the equilibrium by changing the concentrations of the reactants and products. The system responds to this change by shifting the equilibrium position in a direction that minimizes the effect of the disturbance.
In an acidic solution, the addition of H3O+ leads to an increase in the concentration of the complex ion [AlBr3(H2O)]+. To counteract this increase, the equilibrium shifts towards the formation of H2SO3, which consumes AlBr3 and decreases the concentration of the complex ion.
In a basic solution, the addition of H3O+ leads to an increase in the concentration of HSO3-. To counteract this increase, the equilibrium shifts towards the formation of AlBr3, which consumes H2SO3 and decreases the concentration of HSO3-.
Overall, the addition of H3O+ to the equilibrium of the h2so3 albr3 reaction can cause a shift in the equilibrium position towards the formation of either H2SO3 or AlBr3, depending on the acidity or basicity of the solution. This shift is governed by Le Chatelier’s principle, which ensures that the system adjusts to counteract the disturbance and restore equilibrium.

The behavior of aluminum bromide (AlBr3) when it is dissolved in water is a topic of interest in the field of chemistry. In this section, we will discuss the dissociation behavior of AlBr3 and explain whether it dissociates in water.
Discussion on the Dissociation Behavior of AlBr3
When AlBr3 is added to water, it undergoes a dissociation process. This means that the compound breaks apart into its constituent ions. In the case of AlBr3, it dissociates into aluminum ions (Al3+) and bromide ions (Br-). This dissociation can be represented by the following chemical equation:
AlBr3 (s) + H2O (l) → Al3+ (aq) + 3Br- (aq)
The dissociation of AlBr3 in water is driven by the interaction between the compound and the water molecules. Water is a polar molecule, meaning it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. This polarity allows water molecules to surround and solvate the ions formed during the dissociation process.
Explanation of Whether AlBr3 Dissociates in Water
Based on the discussion above, it is clear that AlBr3 does dissociate in water. The presence of water molecules facilitates the breaking apart of the compound into its constituent ions. This dissociation behavior is characteristic of many ionic compounds when they are dissolved in water.
It is important to note that the degree of dissociation of AlBr3 in water can vary depending on factors such as concentration and temperature.

It is an important intermediate in various chemical reactions and is commonly encountered in the form of its aqueous solution. In this section, we will explore the nature of H2SO3 and determine whether it behaves as an acid or a base.
Determination of whether H2SO3 is an acid or a base
To determine whether H2SO3 is an acid or a base, we need to understand its chemical properties and behavior in different reactions. One way to analyze this is by examining its ability to donate or accept protons (H+ ions).
Explanation of its acidic nature
H2SO3 exhibits acidic properties due to its ability to donate protons in chemical reactions. When dissolved in water, it undergoes a partial dissociation, releasing hydrogen ions (H+) into the solution. This dissociation can be represented by the following equation:
H2SO3 ⇌ H+ + HSO3-
In this equation, H2SO3 acts as an acid by donating a proton (H+) to water, forming the bisulfite ion (HSO3-). The presence of hydrogen ions in solution gives it acidic characteristics.
The acidic nature of H2SO3 can also be attributed to the presence of the sulfur atom, which has an oxidation state of +4 in sulfurous acid. This oxidation state allows sulfur to act as a Lewis acid, which is a substance that can accept a pair of electrons during a chemical reaction.
Equilibrium when H3O+ = OH-
Description of the equilibrium state
In a chemical reaction, an equilibrium state is reached when the concentrations of reactants and products remain constant over time. This occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. In the case of H2SO3 and AlBr3, the equilibrium state is achieved when the concentration of H3O+ ions is equal to the concentration of OH- ions.
When H2SO3, also known as sulfurous acid, is dissolved in water, it ionizes to produce H3O+ and HSO3- ions. On the other hand, when AlBr3, which is aluminum bromide, is dissolved in water, it dissociates into Al3+ and Br- ions. These ions can react with each other to form H3O+ and OH- ions through a series of chemical reactions.
The equilibrium state is represented by the equation: H3O+ + OH- ⇌ 2H2O
At this equilibrium, the concentrations of H3O+ and OH- ions are equal, resulting in a neutral solution. This means that the solution is neither acidic nor basic, with a pH of 7.
Explanation of the conditions for H3O+ = OH-
The condition for H3O+ ions to be equal to OH- ions is known as a neutral solution. This occurs when the concentration of H3O+ ions is equal to the concentration of OH- ions. In other words, the concentration of hydronium ions (H3O+) is equal to the concentration of hydroxide ions (OH-).
To achieve this equilibrium condition, the concentration of H3O+ ions can be increased by adding a strong acid to the solution. This will shift the equilibrium towards the formation of more H3O+ ions. Similarly, the concentration of OH- ions can be increased by adding a strong base to the solution, which will shift the equilibrium towards the formation of more OH- ions.
It is important to note that the equilibrium condition of H3O+ = OH- is specific to neutral solutions. In acidic solutions, the concentration of H3O+ ions is greater than the concentration of OH- ions, resulting in a pH value less than 7. Conversely, in basic solutions, the concentration of OH- ions is greater than the concentration of H3O+ ions, resulting in a pH value greater than 7.

Explanation of the balanced equation
Now that we have balanced the equation AlBr3 + K2SO4 = 2KBr + Al2(SO4)3, let’s understand what it represents.
The equation shows a chemical reaction between aluminum bromide (AlBr3) and potassium sulfate (K2SO4). When these two compounds react, they form potassium bromide (KBr) and aluminum sulfate (Al2(SO4)3).

- Balance the atoms: Start by balancing the atoms that appear in the fewest compounds. In this case, we can balance the hydrogen (H) atoms by placing a coefficient of 3 in front of H2SO4, resulting in 6 hydrogen (H) atoms on both sides of the equation.
H2SO4 + Al(OH)3 → 3H2SO4 + Al(OH)3
- Balance the other atoms: Next, balance the oxygen (O) atoms. On the left side of the equation, there are 4 oxygen (O) atoms in H2SO4 and 3 oxygen (O) atoms in Al(OH)3, totaling 7 oxygen (O) atoms. To balance the equation, place a coefficient of 7/4 in front of Al(OH)3.
3H2SO4 + Al(OH)3 → 7/4Al(OH)3 + 3H2SO4
- Simplify the coefficients: Multiply all coefficients by 4 to eliminate fractions.
12H2SO4 + 4Al(OH)3 → 7Al(OH)3 + 12H2SO4
- Check the balance: Finally, verify that the equation is balanced by counting the number of atoms for each element on both sides. In this case, there are 12 hydrogen (H) atoms, 4 sulfur (S) atoms, 28 oxygen (O) atoms, and 4 aluminum (Al) atoms on both sides of the equation.
Explanation of the balanced equation
Now that we have balanced the equation H2SO4 + Al(OH)3 → 7Al(OH)3 + 12H2SO4, let’s delve into its meaning and significance.
The balanced equation represents a chemical reaction between sulfuric acid (H2SO4) and aluminum hydroxide (Al(OH)3). When these two compounds react, they undergo a double displacement reaction, resulting in the formation of aluminum sulfate (Al(OH)3) and sulfuric acid (H2SO4).
Sulfuric acid is a strong acid commonly used in various industrial processes, while aluminum hydroxide is a base. When they react, the hydrogen (H) ions from sulfuric acid combine with the hydroxide (OH) ions from aluminum hydroxide to form water (H2O). This process is known as neutralization.
The balanced equation shows that for every 1 molecule of aluminum hydroxide, 7 molecules of aluminum hydroxide are produced, and for every 1 molecule of sulfuric acid, 12 molecules of sulfuric acid are produced. The coefficients in front of each compound represent the stoichiometric ratios between the reactants and products.
Dissolution of Al2S3 in Water
Aluminum sulfide (Al2S3) is a chemical compound that has garnered interest due to its unique properties and applications. One aspect that researchers have explored is the solubility of Al2S3 in water. In this section, we will discuss the solubility of Al2S3 in water and provide an explanation of whether it dissolves in water.
Discussion on the solubility of Al2S3 in water
The solubility of a compound refers to its ability to dissolve in a particular solvent, such as water. When it comes to Al2S3, its solubility in water is an intriguing topic. To understand this, we need to delve into the chemical properties of Al2S3 and the interactions it undergoes when in contact with water.
Aluminum sulfide is an ionic compound composed of aluminum cations (Al3+) and sulfide anions (S2-). In its solid form, Al2S3 exists as a white crystalline powder. When it is introduced to water, the compound can undergo a chemical reaction known as hydrolysis.
During hydrolysis, water molecules interact with the aluminum and sulfide ions, leading to the formation of aluminum hydroxide (Al(OH)3) and hydrogen sulfide (H2S). This reaction can be represented as follows:
Al2S3 + 6H2O → 2Al(OH)3 + 3H2S
The resulting products of this reaction are aluminum hydroxide, which is a white gelatinous precipitate, and hydrogen sulfide, which is a colorless gas with a distinct odor of rotten eggs.
Explanation of whether Al2S3 dissolves in water
Based on the hydrolysis reaction mentioned above, it is evident that Al2S3 does not dissolve in water in the traditional sense. Instead, it undergoes a chemical reaction that leads to the formation of different compounds. This reaction is irreversible, meaning that once the hydrolysis occurs, it cannot be easily reversed to regenerate Al2S3.
The hydrolysis of Al2S3 is an example of a Lewis acid-base reaction. In this case, Al2S3 acts as a Lewis acid, accepting electron pairs from water molecules to form aluminum hydroxide. The sulfide ions from Al2S3 are protonated by water, resulting in the formation of hydrogen sulfide.
It is important to note that the hydrolysis of Al2S3 is favored in acidic solutions. In an acidic environment, the concentration of hydrogen ions (H+) is higher, promoting the formation of aluminum hydroxide and hydrogen sulfide. However, in basic solutions, the hydrolysis reaction is less favorable.
Weak Acid Nature of H2SO3
Sulfurous acid (H2SO3) is considered a weak acid due to its limited ability to dissociate in water. In this section, we will explore why H2SO3 is classified as a weak acid and discuss its dissociation behavior.
Explanation of why H2SO3 is considered a weak acid
When we refer to the strength of an acid, we are essentially referring to its ability to donate protons (H+) in an aqueous solution. Strong acids, such as hydrochloric acid (HCl) or sulfuric acid (H2SO4), readily dissociate in water, releasing a large number of H+ ions. On the other hand, weak acids like H2SO3 only partially dissociate, resulting in a smaller concentration of H+ ions in solution.
The weak acid nature of H2SO3 can be attributed to the stability of its molecular structure. Sulfurous acid consists of two hydrogens (H) bonded to a sulfur (S) atom, which is further connected to two oxygen (O) atoms. The sulfur atom in H2SO3 has an oxidation state of +4, and the molecule adopts a bent structure.
Due to this molecular structure, the oxygen atoms in H2SO3 can exert a significant electron-withdrawing effect on the hydrogen atoms. This effect makes it more difficult for the hydrogen atoms to dissociate and release H+ ions. As a result, H2SO3 exhibits a relatively low acidity compared to strong acids.
Discussion on its dissociation behavior
When H2SO3 is dissolved in water, it undergoes a partial dissociation, resulting in the formation of sulfite ions (SO3^2-) and H+ ions. The dissociation reaction can be represented as follows:
H2SO3 ⇌ H+ + HSO3^-
In this equilibrium reaction, only a fraction of the H2SO3 molecules dissociate into H+ ions and HSO3^- ions. The HSO3^- ions can further react with water to form sulfite ions (SO3^2-):
HSO3^- + H2O ⇌ H3O+ + SO3^2-
The equilibrium constant for the dissociation of H2SO3 is relatively small, indicating that the dissociation is incomplete. This limited dissociation results in a lower concentration of H+ ions in the solution, making H2SO3 a weak acid.
It is important to note that the strength of an acid is not solely determined by its molecular formula but also by its concentration in solution. Even though H2SO3 is a weak acid, it can still exhibit acidic properties when present in sufficient concentration.
