• # question_answer When electric current is passed through an ionic hydride in the molten state A) Hydrogen is liberated at the anode B) Hydrogen is liberated at the cathode C) No reaction takes place D) Hydride ion migrates towards cathode

${{M}^{+}}{{H}^{-}}\to {{M}^{+}}+\underset{\text{Hydride ion}}{\mathop{{{H}^{-}}\ \ }}\,$ ${{H}^{-}}\to \frac{1}{2}{{H}_{2}}+{{e}^{-}}$(At anode)
