Metallic magnesium is prepared by

A

Reduction of MgO by coke

B

Electrolysis of aqueous solution of `Mg(NO_(3))`

C

Displacement of Mg by iron from `MgSO_(4)`solution

D

Electrolysis of molten `MgCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`underset("(Molten)")(MgCl_(2))overset("Electrolysis")to underset("Cation")(Mg^(+2))+ underset("Anion")(2Cl)`
Anonde -`2Cl^(-) to 2Cl + 2e^(-) , Cl + Cl to Cl_(2)`
Cathode -`Mg^(+2) +2e^(-) to Mg`
