Question

Name the compounds of calcium which are used in making washing soda.

Answer 1

• Solvay’s process is used to synthesize washing soda. In Solvay’s method, sodium chloride, ammonia, and carbon dioxide react in water.
• Calcium carbonate is utilized to make carbon dioxide, and the remaining calcium oxide is used to recover ammonia from ammonium chloride.
• Sodium bicarbonate is first obtained, which is then heated to produce sodium carbonate.
• At last, sodium carbonate is recrystallized to make washing soda.
• Chemical formula of washing soda : ${\mathrm{Na}}_2{\mathrm{CO}}_3$.
