Solution

Differences between washing soda and baking soda:
Washing soda Baking Soda
1. Chemical formula is Na₂CO₃ (sodium carbonate) 1. Chemical formula is NaHCO₃ (sodium bicarbonate)
2. pH 11.0 (basic caustic soda) used as cleaning agent and in laundry but never in food. 2. pH is 7 (neutral) and is best used as leaving agent in cooking.
3. It does not evolves carbon dioxide gas on heating but looses its water of crystallization. 3. It looses water and releases carbon dioxide on heating and forms washing soda. NaHCO₃ -> Na₂CO₃ + H₂O + CO₂
