An aqueous solution of sodium chloride is called brine. The method in which sodium hydroxide is manufactured by electrolysis of an aqueous solution of sodium chloride ( called brine) is called chlor-alkali process because the products of electrolysis are chlorine and caster and kellner cell.

Answer 2

Answer:

Brine is a high-concentration solution of salt (NaCl) in water (H2O). In different contexts, brine may refer to salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).

It is prepared by Solvay's process. (1) A cold and concentrated solution of sodium chloride is reacted with ammonia and carbon dioxide to obtain sodium hydrogen carbonate. (2) Sodium hydrogen carbonate is separated by filtration,dried and heated. Oh heating sodium hydrogen carbonate decomposes to form sodium carbonate.
