A) electrolysis of molten \[CaC{{l}_{2}}\]
B) electrolysis of solution of \[CaC{{l}_{2}}\] in water
C) reduction of \[CaC{{l}_{2}}\] with carbon
D) roasting of lime stone
Correct Answer: A
Solution :
Calcium is manufactured by the electrolysis of a molten mixture of calcium chloride containing some \[Ca{{F}_{2}}\] \[CaC{{l}_{2}}C{{a}^{2+}}+2C{{l}^{-}}\] \[C{{a}^{2+}}+2{{e}^{-}}\to Ca\](at cathode)
