Question

What is a washing soda ? what is the preparation method ?​

Answer 1

Answer:

Preparation of Washing Soda

Washing soda is synthesized through Solvay's process. Solvay's process involves the reaction of sodium chloride, ammonia and carbon dioxide in water. Carbon dioxide involved is produced through calcium carbonate and the calcium oxide left is used in recovering ammonia from ammonium chloride.

Answer 2

Answer:

Washing Soda :-

Sodium carbonate, Na₂CO₃·10H₂O, is the inorganic compound with the formula Na₂CO₃ and its various hydrates. All forms are white, odourless, water-soluble salts that yield moderately alkaline solutions in water. Historically, it was extracted from the ashes of plants growing in sodium-rich soils.

Preparation of Washing Soda:-

Solvay's process involves the reaction of sodium chloride, ammonia and carbon dioxide in water. ... At first, sodium bicarbonate is obtained which is then converted to sodium carbonate on heating. Finally, washing soda is produced by recrystallization of sodium carbonate.
