Carbonic Acid and Sodium Hydroxide

H₂CO₃ + 2NaOH → Na₂CO₃ + 2H₂O

Visão geral

Carbonic acid, formed when CO₂ dissolves in water, reacts with two equivalents of sodium hydroxide to form sodium carbonate. This is the basis of CO₂ scrubbing with alkali solutions. The first neutralization produces sodium bicarbonate, and the second converts it to carbonate.
