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 a solution `CaCl_(2)`

Text Solution

Verified by Experts

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