Question

) Write chemical equation for the preparation of
washing soda and also write its on use.
​

Answer 1

Answer:

Baking soda or sodium hydrogen carbonate produces sodium carbonate upon heating and further produces washing soda along with carbon dioxide and water, on recrystallization. The chemical formula for this is as follows: 2NaHCO3 heating  Na2CO3 + CO2 + H2O

Answer 2

Answer:

The key reaction in Solvay synthesis is, NaCl+NH3+Co2+H2O→NaHCO3(s)+NH4Cl. in which a sodium chloride solution (brine) is saturated with ammonia gas (NH3), then with carbon dioxide, and finally cooled. This is a precipitation reaction in which solid sodium bicarbonate, NaHCO3, comes out of solution.

It's called Solvay process.

Sodium bicarbonate is an antacid used to relieve heartburn and acid indigestion. Your doctor also may prescribe sodium bicarbonate to make your blood or urine less acidic in certain conditions. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
