Statement-1:Sodium chloride is added during electrolysis of fused anhydrous magnesium chloride.
Statement-2:Anhydrous magnesium chloride is obtained by heating hydrated magnesium chloride, `MgCl_2. 6H_2O`

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
C
S-1:It lowers the fusion temperature of `MgCl_2` and provide conductivity to the elecrolyte.
S-2: `MgCl_2. 6H_2O` is calcined in a stream of dry HCl gas to have anhydrous `MgCl_2` . In absence of dry HCl. It forms `Mg_2OCl_2 (MgO. MgCl_2)` because of hydrolysis .
