Question

Explain the formation of sodium carbonate

Answer 1

Answer:

Formation of sodium carbonate

step 1_The sodium hydrogencarbonate is heated in rotating ovens at 450 K so that it decomposes to sodium carbonate, water and carbon dioxide. step 2_The product of the process, anhydrous sodium carbonate, is obtained as a fine white powder known as light sodium carbonate.

Sodium Carbonate is also produced from an aqueous solution of NaCl by Solvay process. .

In Castner-Kellner method, Sodium hydroxide (NaOH) or caustic soda is prepared by the electrolysis of aqueous solution of NaCl, also called as salt water brine. Sodium and chlorine gas are produced in this process.
