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

  1. A preventing the corrosion of electrolytic cell
  2. B preventing the mixing of \(\mathrm{H}_2\) and \(\mathrm{F}_2\)
  3. C as anode
  4. D as cathode
Verified Solution

Answer & Solution

Correct Answer

(B) preventing the mixing of \(\mathrm{H}_2\) and \(\mathrm{F}_2\)

Step-by-step Solution

Detailed explanation

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
