Question

What is the role of diaphragm in the electrolysis of aqueous sodium chloride solution?

Answer 1

1. In the process of electrolysis, if chlorine comes into contact with hydrogen, it produces a mixture which will explode violently on exposure to sunlight or heat.
2 Hydrogen chloride gas would be produced. Obviously, the two gases need to be kept apart.
3. The diaphragm and membrane cells are designed so that all the products are kept separate.
