What is one important use of the gas formed at the anode in the chlor-alkali process?

Answer and explanation

Correct answer: Disinfecting water

The governing concept is electrolysis of concentrated brine in the chlor-alkali process. At the anode, chloride ions are oxidised and chlorine gas is released: 2Cl⁻ → Cl₂ + 2e⁻. Chlorine is a strong disinfectant because it forms substances such as hypochlorous acid in water, which destroy many disease-causing microorganisms. Hence chlorine is used to disinfect drinking-water supplies and swimming pools, making option B correct. Carbon dioxide, not chlorine, is associated with raising cakes.
