Vedclass · Answer

(A) When electric current is passed through an ionic hydride in the molten state,hydrogen gas is liberated at the anode. In hydrides of $s-$block elements,hydrogen exists in the $-1$ oxidation state. It is oxidized to hydrogen gas $(H_2)$ at the anode because oxidation always occurs at the anode. The reaction is: $2H^{-} \rightarrow H_2 + 2e^{-}$ (at anode)
