Hydrochloric Acid and Sodium Carbonate

2HCl + Na2CO3 → 2NaCl + H2O + CO2

نظرة عامة

Hydrochloric acid reacts with sodium carbonate (washing soda) to produce sodium chloride, water, and carbon dioxide gas. The carbonate ion is a Brønsted base that accepts two protons. The reaction proceeds in two steps: first forming bicarbonate, then decomposing carbonic acid to CO₂ and water.
