CHEMICAL FORMULA OF bleaching powder is CaOCl2.                                      2. chemical formula of plaster of paris is CaSO4. 1/2 H2O.                                        3. chemical formula of washing soda is  Na2CO3.10H2O.                                          b) Baking soda ( sodium carbonate or sodium hydrogen carbonate)  formula is    NaHCO3. when it is heated it easily loses CO2 and the CO2 makes bubbles and this creates channels, which is what gives baked  goods a fluffy and light texture.

the trapped CO2 bubbles are what allowed the baked goods to rise.                   c)  the main ingredient of baking soda is sodium bi   carbonate.  sodium bi carbonate is a base which reacts with bases like vinegar, yogurts etc.
