Decomposition of Sodium Bicarbonate

2NaHCO3 → Na2CO3 + H2O + CO2

Genel Bakış

Sodium bicarbonate (baking soda) decomposes when heated above 50 C into sodium carbonate, water, and carbon dioxide. This thermal decomposition is the key reaction in baking, where the released CO2 gas creates the bubbles that make baked goods rise.
