Question 5

What is the balanced half-equation for the formation of chlorine from chloride ions?

A

Cl−−e−→Cl{\text{Cl}}^- - {\text{e}}^- \rightarrow {\text{Cl}}Cl−−e−→Cl

B

Cl−→Cl−e−{\text{Cl}}^- \rightarrow {\text{Cl}} - {\text{e}}^-Cl−→Cl−e−

C

2Cl−−2e−→Cl22{\text{Cl}}^- - 2{\text{e}}^- \rightarrow {\text{Cl}}_22Cl−−2e−→Cl2​

D

2Cl−→Cl2−2e−2{\text{Cl}}^- \rightarrow {\text{Cl}}_2 - 2{\text{e}}^-2Cl−→Cl2​−2e−
