Answer to Question #167182 in General Chemistry for Zarrin

Question

during the electrolysis of magnesium chloride, magnesium is formed. Complete the half equation of the following reaction. Mg2+. chlorine is also formed at the anode. complete the half equation to the following reaction.

Answer 1

The half reactions of Magnesium chloride $MgCl_2$ are-

At Cathode:- Magnesium ion is reduced to solid Magnesium.

$\text {Mg}_{(aq)}^{2+}+2\text{e}^{-}\rightarrow\text{Mg}_{(s)}$

At Anode:- Chlorine ion is oxidised to form chlorine gas.

$2\text{Cl}^-_{(aq)}\rightarrow \text{Cl}_{2(g)}+2\text{e}^-$
