Question

What happens when sodium hydrocarbonate is heated?

Answer 1

2NaHCO3-------》Na2CO3 + H2O + CO2

Answer 2

so here is your answer...

Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide. This type of reaction is called a thermal decomposition.

On prolonged boiling of the solution, the bicarbonate will almost entirely get converted to the more stable carbonate with the liberation of carbon dioxide, just like it happens when the pure or dry salt is heated. Usually, solid sodium bicarbonate decomposes in correspondence to the above equation.
