Sodium Carbonate and Hydrochloric Acid
Na2CO3 + 2HCl → 2NaCl + H2O + CO2
Обзор
Sodium carbonate reacts with hydrochloric acid to produce sodium chloride, water, and carbon dioxide gas. The effervescence from CO2 evolution is a characteristic feature. This reaction is used to test for carbonate ions and occurs in two stages through bicarbonate intermediate.
