Question

explain preparation of baking soda​

Answer 1

Explanation:

when an access of carbon dioxide is bubbled through a nearly saturated solution of common salt containing ammonia, ammonium hydrogen carbonate is formed. This will react with more of sodium chloride to form sparingly soluble sodium hydrogen carbonate and ammonium chloride. Nacl+H2O + Co2+ NH3 give out NaHco3+NH4cl.

sodium hydrogen carbonate is separated by filtration. It is then washed

with cold water and dried in air.
