Why is the membrane considered important in the chlor-alkali process?

Answer and explanation

Correct answer: To prevent products from mixing and causing unwanted reactions

In the chlor-alkali process, electrolysis of concentrated brine produces chlorine at the anode, hydrogen at the cathode, and sodium hydroxide in solution. A membrane separates the electrode compartments and limits contact between chlorine and sodium hydroxide, which could otherwise react to form unwanted products. It does not remove all water or deposit sodium metal. Therefore option A correctly states its purpose.
