Question

Fluorine cannot be obtained by the electrolysis of aq KF with inert electrodes. Justify

Answer 1

Explanation:

Anhydrous HF does not work because it is a poor conductor of electricity (much like distilled water). When Henri Moissan first isolated fluorine, he used a mixture of potassium bifluoride and hydrogen fluoride. The former is an ionic compound so it causes the solution to become a good conductor.
