The role of copper diaphragm in Whytlaw-Gray's method is

The role of copper diaphragm in Whytlaw-Gray's method is
  1. preventing the corrosion of electrolytic cell
  2. preventing the mixing of $\mathrm{H}_2$ and $\mathrm{F}_2$
  3. as anode
  4. as cathode

Solution

In Whytlaw-Gray's method for preparation of fluorine, the copper diaphragm is used to prevent the mixing of $\mathrm{H}_2$ and $\mathrm{F}_2$ liberated at cathode and anode respectively. Reactions in the electrolytic cell
