Why is it necessary to keep the products separate in the chlor-alkali process?

Answer and explanation

Correct answer: They may undergo unwanted reactions if mixed

Electrolysis of brine produces hydrogen at the cathode, chlorine at the anode, and sodium hydroxide in the solution. Hydrogen and chlorine can react explosively in the presence of suitable conditions, while chlorine can also react with sodium hydroxide to form hypochlorite or chlorate products. Separating the electrode products prevents contamination and unwanted reactions, so option A is correct. The other statements do not give the chemical reason.
