• B. preventing the mixing of $H _{2}$ and $F _{2}$
• C. as anode
• D. as cathode

Answer 1

Answer: (B)

In Whytlaw-Gray's method for preparation of fluorine, the copper diaphragm is used to prevent the mixing of $H _{2}$ and $F _{2}$ liberated at cathode and anode respectively. Reactions in the electrolytic cell
