The chlor-alkali process is carried out by electrolysis of what?
Answer and explanation
Correct answer: Brine
Brine is a concentrated aqueous solution of sodium chloride. During its electrolysis, chloride ions are discharged at the anode to produce chlorine, while water is reduced at the cathode to produce hydrogen and hydroxide ions. The remaining sodium ions combine with hydroxide ions to form sodium hydroxide. This complete process is therefore called chlor-alkali electrolysis, making option A correct.
