Which statement about the reactions of halogens with halide ions is correct?
Br2(aq)\text{Br}_2\text{(aq)}Br2(aq) can oxidise Cl−(aq)\text{Cl}^-\text{(aq)}Cl−(aq).
Cl−(aq)\text{Cl}^-\text{(aq)}Cl−(aq) can reduce Br2(aq)\text{Br}_2\text{(aq)}Br2(aq).
I−(aq)\text{I}^-\text{(aq)}I−(aq) can reduce Br2(aq)\text{Br}_2\text{(aq)}Br2(aq).
Br2(aq)\text{Br}_2\text{(aq)}Br2(aq) can reduce I−(aq)\text{I}^-\text{(aq)}I−(aq).
