Formation of Sodium Bicarbonate

NaOH + CO2 → NaHCO3

概要

Sodium hydroxide reacts with carbon dioxide in a 1:1 ratio to form sodium bicarbonate (baking soda). This is one of the steps in the Solvay process for producing sodium carbonate. The reaction is important in carbon dioxide scrubbing systems.
