Question 13
H

Which half equation occurs at the cathode during electrolysis of copper chloride solution?

[1]
A

2Cl−→Cl2+2e−\mathrm{2Cl^-\rightarrow Cl_2+2e^-}2Cl−→Cl2​+2e−

B

Cu→Cu2++2e−\mathrm{Cu\rightarrow Cu^{2+}+2e^-}Cu→Cu2++2e−

C

Cu2++2e−→Cu\mathrm{Cu^{2+}+2e^-\rightarrow Cu}Cu2++2e−→Cu

D

Cl2+2e−→2Cl−\mathrm{Cl_2+2e^-\rightarrow 2Cl^-}Cl2​+2e−→2Cl−
