Carbonic Acid and Sodium Hydroxide

H2CO3 + 2NaOH → Na2CO3 + 2H2O

概要

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.
