Reaction of halogens and coper

Chlorine is more reactive than bromine. When chlorine gas is passed through a solution of copper(II) bromide, chlorine displaces bromine.

$$\text{Cl}_2\text{(g)} + \text{CuBr}_2\text{(aq)} \rightarrow \text{CuCl}_2\text{(aq)} + \text{Br}_2\text{(aq)}$$

Bromine is more reactive than iodine. When bromine water is added to a solution of copper(II) iodide, bromine displaces iodine.

$$\text{Br}_2\text{(aq)} + \text{CuI}_2\text{(aq)} \rightarrow \text{CuBr}_2\text{(aq)} + \text{I}_2\text{(aq)}$$
