Answer:
Washing soda is used in glass, soap and paper industries.
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 heating sodium hydrogencarbonate (NaHC03), it decomposes to form sodium carbonate (Na2C03), water(H20) and carbon dioxide (C02).
