During electrolysis of fused calcium hydride, the hydrogen is produced

1.	During electrolysis of fused calcium hydride, the hydrogen is produced atA. CathodeB. AnodeC. Hydrogen is not liberated at allD. `H_(2)` produced reacts with oxygen to form water.
Answer» Correct Answer - b `CaH_(2)overset(El ectrolysis)rarrCa^(2+)+2H^(c-)` At cathode `(` reduction `):Ca^(2+)+2e^(-) rarr Ca` At anode `(` oxidation`):2H^(c-) rarr H_(2)+2e^(-)`
