Calcium is obtained by

A

Roasting of lime stone

B

Reduction of `CaCl_(2)` with carbon

C

Electrolysis of a solution of `CaCl_(2)` in water

D

Electrolysis of molten `CaCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`CaCl_(2)tounderset("Cathode")(Ca^(+2))+underset("Anode")(2Cl^(-))`
Cathode : `Ca^(+2)+2e^(-)toCa`
Anode : `2Cl^(-)to2e^(-)+Cl_(2)`.
