The role of copper diaphragm in Whytlaw-Gray's method is
- A preventing the corrosion of electrolytic cell
- B preventing the mixing of \(\mathrm{H}_2\) and \(\mathrm{F}_2\)
- C as anode
- D as cathode
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
