Sodium Bicarbonate and Hydrochloric Acid

NaHCO3 + HCl → NaCl + H2O + CO2

Aperçu

Sodium bicarbonate (baking soda) reacts with hydrochloric acid to produce sodium chloride, water, and carbon dioxide gas. The bicarbonate ion acts as a base, accepting a proton to form carbonic acid, which immediately decomposes to water and CO₂. The effervescence is characteristic of bicarbonate-acid reactions.

Exemple du quotidien

Baking soda is used as a quick antacid remedy at home, and in baking where it reacts with acidic ingredients to produce CO₂ that makes dough rise.

Importance industrielle

Sodium bicarbonate is used in fire extinguishers (the CO₂ smothers flames), in water treatment, and as a cleaning agent. Annual production exceeds 1 million tonnes.
