Sulfuric Acid and Sodium Hydroxide Neutralization
H2SO4 + 2NaOH → Na2SO4 + 2H2O
Overview
Sulfuric acid, a diprotic acid, requires two moles of sodium hydroxide for complete neutralization. The reaction produces sodium sulfate (Glauber's salt) and water. Partial neutralization with one mole of NaOH would produce sodium bisulfate (NaHSO₄) instead.
Participants
| Role | Substance | Coefficient | State |
|---|---|---|---|
| Reactant | Sulfuric Acid H₂SO₄ | 1 | (aq) |

Everyday Example
Sodium sulfate produced by this neutralization is used as a filler in powdered laundry detergents.
Industrial Importance
Sodium sulfate is used in the Kraft process for paper manufacturing, in glass production, and as a raw material for sodium sulfide. Annual production exceeds 6 million tonnes.
