Decomposition of Sodium Bicarbonate

2NaHCO3 → Na2CO3 + H2O + CO2

نظرة عامة

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.

مثال من الحياة اليومية

When baking soda is added to cake batter and heated in the oven, this decomposition releases CO2 bubbles that make the cake fluffy and light.

الأهمية الصناعية

This reaction is fundamental to the baking industry. Sodium bicarbonate is also used in fire extinguishers, where the CO2 released helps smother flames.
