Question

explain alkali process in a brief with diagram

Answer 1

When electricity is passed through an aqueous solution of sodium chloride it decomposes to form sodium hydroxide. The process is called the chlor-alkali alkali process because of the products formed: chlor for chlorine and alkali for Sodium Hydroxide. Chlorine gas is given off at the anode and hydrogen gas at the cathode.

An aqueous solution of sodium chloride is called brine.

2NaCl (aq) + 2H2O(l) ---(electrolysis)---> 2NaOH(aq) + Cl2(g) + H2(g).
