Sodium Hydroxide and Sulfuric Acid

2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

Aperçu

Sodium hydroxide reacts with sulfuric acid to form sodium sulfate and water. This is a standard acid-base neutralization producing a neutral salt. Sodium sulfate (Glauber's salt) was one of the first chemicals produced industrially.
