Question

Carnallite on electrolysis gives:

• A. $Mg$ and $C{l}_2$
• B. $Ca$ and $C{l}_2$
• C. $K$ and $C{l}_2$
• D. $Al$ and $C{l}_2$

Answer 1

The correct option is C $K$ and $C{l}_2$

Carnallite is an ore of Potassium.$KCl.Mg{Cl}_2.6H_{2}O$.

Electrolysis of fused $KCl$ and $Ca{Cl}_2$ is carried out to obtain Potassium

$KCl\rightleftharpoons K^{+}+{Cl}^{-}$
At Cathode: $K^{+}+e^{-}\to K$

At Anode: $2{Cl}^{-}\to {Cl}_2+2e^{-}$
