B. Baking soda is sodium bicarbonate which is basic in nature and used as an antacid.
NaHCO3
C. Sodium carbonate which has a common name washing soda, a monohydrate which is used in the preparation of glass. It is used to flux silica by lowering down the temperature.
Two forms of sodium carbonate are used i.e heavy and light. The light form is obtained first and is converted to heavy form. The heavy form is is used as a solid in making glass where it is used as flux in the melting of silica.Na2CO3H2O
D. The electrolysis of aqueous solution of sodium chloride gives hydrogen at the cathode and chlorine at the anode. This solution is called as the brine solution. It helps in the evolution of hydrogen gas and chloride gas.
