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.
How to balance NaOH + H2so4?
The process of balancing chemical equations involves matching the number of atoms in a reactant and product. The reactants in this reaction are sulfuric acid, one of the strongest acids, and sodium hydroxide, one of the strongest bases.
Salt and water are the end products, This reaction is known as a neutralization reaction.
The following is the reaction’s equation:
NaOH + H2SO4→ Na2SO4 + H2O
Make a table to compare the no. of reactant and product on both sides of the equation.
| Atoms are present in molecules that participate in reactions. | In the Reactant | In the Product |
|---|---|---|
| Na | 1 | 2 |
| O | 5 | 5 |

To equalize Na and H, we will start with Na and use 2 as the coefficient for NaOH.
H2SO4 + 2NaOH → Na2SO4 + H2O
Now that there are 4 H atoms on the reactant side, use 2 as the coefficient value for H2O. H2SO4 + 2NaOH → Na2SO4 + 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:
- Pipette a 250mL flask with an aliquot of sulphuric acid solution
- Dilute to about 100 mL with distilled water.
- Add a couple of drops of phenolphthalein solution to the mix.
- Titrate with NaOH solution until the color changes for the first time.
- 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.
