Vedclass · Answer

(C) $Mg$ is a highly reactive metal. During the electrolysis of an aqueous solution of $MgCl_2$,$H_2$ gas is evolved at the cathode instead of $Mg$ because the reduction potential of water is higher than that of $Mg^{2+}$ ions. Therefore,$Mg$ is obtained by the electrolysis of molten $MgCl_2$ (fused salt) to prevent the discharge of hydrogen ions.

$Mg$ is obtained by:
