Question

State True or False.

In the electrolysis of fused calcium hydride, hydrogen is liberated at cathode.

• A. True
• B. False

Answer 1

The correct option is B False

Electrons come off the cathode and travel to the anode. So the calcium would be attracted to the cathode and deposited there. The $H^{-}$ would move toward the anode and the extra electron would be released causing $H_2$ to bubble
At cathode:$C{a}^{2+}+2e^{-}\to Ca$
At anode:$2H^{-}\to H_2+2e^{-}$.
So the given statement is false.
Hence option B is correct.
