Assertion (A): Magnesium can be obtained by the electronlysis of aqueous solution of `MgCl_(2)`.
Reason (R ): The electrode potential of `Mg^(2+)` is much higher than `H^(o+)`.

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`.
B. If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R )` is incorrect.
D. If `(A)` is incrrect, but `(R )` is correct.

Answer

D

Explanation

Correct assertion: Magnesium can be obtained by the electrolysis of fused `MgCl_(2)`.
Correct reason: the electrode potential of `Mg^(2+)` is much lower than `H^(o+)`.
