Explanation:
The chemical name of baking soda is sodium hydrogen carbonate.
The formula of baking soda is NaHCO3.
It is prepared by reaction of cold and concentrated solution of sodium chloride with ammonia and carbon dioxide.
(1) It is a white crystal which are sparingly soluble in water.
Answer:
Preparation of Baking Soda
Solvay process is used for the production of sodium bicarbonate and sodium carbonate industrially. In this process carbon dioxide, water, ammonia and brine solution in its concentrated form, are used as raw materials. This process is used mainly because it is inexpensive and less number of raw materials are used to produce necessary chemicals. The important chemical reaction that is used in the production of baking soda and sodium carbonate is:
CO2+H2o+NH3+Na+ → NaHCO3+NH+4
NaHCO3 → Na2CO3+CO2+H2O
Carbon dioxide produced is recycled to produce NaHCO3
Properties of Sodium Bicarbonate
It is non-flammable.
Powder dust is not as explosive.
It has a melting point of 500
NaHCO3 is a white crystalline solid which is odourless.
It is basic in nature.
