Question

Why F2 is not by electrolysis of aqueous HF ?​

Answer 1

Answer:

1. In an aqueous solution, as compared to F- ions, H2O is more easily oxidized to give O2 gas.

2. Though it is a good conductor of electricity.

3. Therefore, F2 cannot be obtained by electrolysis of an aqueous HF solution.

4. Fluorine is obtained by the electrolysis of a solution of potassium hydrogen difluoride in anhydrous hydrofluoric acid.

Answer 2

1. In an aqueous solution, H2O is more quickly oxidised to produce O2 gas than F- ions.

2. Despite the fact that it is an excellent conductor of electricity.

3. As a result, electrolysis of an aqueous HF solution does not yield F2.

4. Fluorine may be made by electrolyzing a potassium hydrogen difluoride solution in anhydrous hydrofluoric acid.
