7 Facts on Naoh + H2so4: With Several Elements Reaction


This article is about the naoh + h2so4(Reaction mixture) and explains how a reaction occurs, product formation, balancing, and how to proceed with titration of given mixtures.

Sodium hydroxide reacts with sulphuric acid and has chemical formula is Naoh+h2so4 producing the product of (NaSO4+H2O) Sodium sulphate and water. This is an acid-base reaction and the product obtained is in form of salt and water. Sodium sulphate is salt(product of neutralization reaction). Thus when an acid reacts with a base a neutralization reaction happens and gives the product as salt and water molecules released.

                                2NaOH + H2SO4  → Na2SO4 + 2H2O

What happens when NaOH reacts with H2so4?

When NaOH reacts with H2SO4, their is formation of salt takes place and water molecules are also released as a side product. The reaction is as follows:

                         NaOH      +    H2SO4       →     Na2SO4          +       H2O

                        Sodium         Sulphuric       Sodium              Water

                      Hydroxide          Acid             Sulphate

The reactant is Sodium Hydroxide and Sulphuric acid with the chemical formula NaOH and H2SO4. This is an acid-Base reaction which is called a neutralization reaction and the formation of salt as a product takes place.

During the neutralization reaction, the base neutralized the acid, and heat is released thus the reaction is called an Exothermic reaction and a new bond formation takes place.

What kind of reaction is NaOH + H2so4?

Consider the reaction between a strong base and a strong acid. Sulphuric acid is a strong acid, and sodium hydroxide is a strong base.

Acid + Base → Salt + water(Neutralization reaction), When strong acid(H2SO 4)reacts with a strong (NaOH) base a neutralization reaction is observed. 

                       H2SO4 + 2NaOH  → Na2SO4 + 2H2O

It is very spontaneous and always their formation of salt and water. As a strong acid, H2SO4 produces H+ ions, which are attacked by the OH- of NaOH, resulting in the formation of water. Na+ ions form ionic bonds with sulphate ions to form Na2SO4 (salt).

This also shows Double displacement reactions, this occurs when two compounds react together by exchanging ions, resulting in the formation of two new compounds. Positive ions are exchanged for negative ions in these reactions.

Naoh + h2so4 net ionic equation

By using the ionic equation, we can find out the spectator ions by splitting each reactant and product molecule.

Following are the steps to writing the Net ionic equation:

1. Write the molecular equation in a balanced form. 

H2SO4 + 2NaOH → Na2SO4  + 2H2O.

2. Assign the state(solid(s), liquid(l), gas(g), and aqueous(aq) state) to each substance.

H2SO4 + 2NaOH → Na2SO4  + 2H2O

3. Split each ion in its ionic form.

H2SO4 → 2H+ + (SO4)2-

NaOH → Na+ + (OH)

Na2SO4 → 2Na+ + (SO4)2-

2H+ (SO4)2- + 2Na+ + 2(OH) → 2Na+ +(SO4)2-+ 2H2O

Now found the spectator ions and remove them, We can see that Na+ and(SO4)2-appear on both sides of the equation, and they can be removed.

5. Write the net ionic equation.

2H+  + 2 (OH)→ 2H2O

As the net ionic equation is 2H+  + 2(OH) → 2H2O.

NaOH + h2so4 titration

The acid-base titration method is used to determine the concentration (molarity unknown) of an acid or base by neutralizing it with a known concentration base or acid (molarity).

Let’s take an example of NaOH + H2SO4 titration for determining the concentration of NaOH or H2SO4

Thus the overall balanced chemical neutralized reaction is: H2SO4+ 2NaOH → Na2SO4 + 2H2O

Steps used in titration:

NaOH + h2so4  titration indicator

During NaOH + H2SO4 titration we should use Phenolphthalein as the indicator for the acid-base titration.

NaOH + h2so4 titration calculations

Let’s calculate the molarity or concentration of the H2SO4 solution. The general equation for calculation of molarity of given solution: 

M1V1 = M2V2

  • where M1 (molarity of H2SO4 ) =?
  • M2 (molarity of NaOH) = xmol/L
  • V1 ( volume of  H2SO4) = y mL
  • V2 ( volume of NaOH) = z mL

M1=M2V2/V1,

Firstly we calculate No. of moles of NaOH= M×L= xmol/L× y mL =N mol NaOH.

N mol of NaOH×1mol H2SO4/ 2mol NaOH =Y mol H2SO4, M1=Y M 

M1 = Y M ( molarity of H2SO4).

NaOH + h2so4 titration experiment

Apparatus used: Rubber tubing is attached to a burette pipette syringe, a beaker with a capacity of 1–250 mL, Beakers 3–100 mL, a Burette clamp, and a grease pencil stand. Each beaker must be completely dry and clean.

One 100 mL beaker should be labeled for Acid, one for Base, and one for Rinse.

Procedure:

  1. Pipette a 250mL flask with an aliquot of sulphuric acid solution
  2. Dilute to about 100 mL with distilled water.
  3. Add a couple of drops of phenolphthalein solution to the mix.
  4. Titrate with NaOH solution until the color changes for the first time.
  5. Repeat the experiment 3-4 times for obtaining a reading.

NaOH + h2so4 titration curve

An S-shaped curve is produced by titrating a strong acid with a strong base. The curve is asymmetrical because the solution becomes more dilute as the volume of the solution steadily increases during the titration. 

Thus Naoh+ H2so4 Has an S-shaped curve.

NaOH + h2so4 titration colour

NaOH + h2so4 titration colour is the pink solution after endpoint.

What is the equivalence point of NaOH + h2so4 titration?

The amount of titrant added is just enough to completely neutralize the analyte solution at this point in the titration. In an acid-base titration, moles of base equal moles of acid, and the solution contains only salt and water at the equivalence point. 

Thus moles of NaOH= moles of H2SO4, and the equivalence point is obtained at pH=7.

Conclusion

According to the reaction equation, H2SO4 + 2NaOH → Na2SO4 + 2H2O

The ratio of sulfuric acid to sodium hydroxide is 1:2. That means the number of moles of sulfuric acid used is half that of sodium hydroxide.
