Question 14
H

Chlorine reacts with iron(II) ions in solution.

2Fe2++Cl2→2Fe3++2Cl− \mathrm{2Fe^{2+} + Cl_{2} \rightarrow 2Fe^{3+} + 2Cl^{-}} 2Fe2++Cl2​→2Fe3++2Cl−

Which statement is correct?

[1]
A

Iron(II) ions lose electrons and are reduced; chlorine gains electrons and is oxidised.

B

Iron(II) ions lose electrons and are oxidised; chlorine gains electrons and is reduced.

C

Iron(II) ions gain electrons and are reduced; chlorine loses electrons and is oxidised.

D

Iron(II) ions gain electrons and are oxidised; chlorine loses electrons and is reduced.
