Vedclass · Answer

(A) Calcium is an alkaline earth metal with a high negative reduction potential. It cannot be obtained by the reduction of its salts with carbon or by the electrolysis of its aqueous solution because hydrogen gas would be evolved at the cathode instead of calcium. Therefore,calcium is commercially prepared by the electrolysis of fused (molten) $CaCl_2$ containing a small amount of $CaF_2$ to lower the melting point.
