A) hydrogen is liberated at cathode
B) hydrogen is liberated at anode
C) there is no reaction
D) \[{{H}^{-}}\]ions produced, migrate to the cathode
Correct Answer: B
Solution :
In this process, hydrogen liberates at anode, e.g., \[Mg{{H}_{2}}\xrightarrow{electrolysis}M{{g}^{2+}}+2{{H}^{-}}\] At anode: \[2{{H}^{-}}\xrightarrow{{}}{{H}_{2}}\uparrow +\,2{{e}^{-}}\] At cathode: \[M{{g}^{2+}}+2{{e}^{-}}\xrightarrow{{}}Mg\]
