When chlorine gas is bubbled through a potassium bromide solution, a displacement reaction occurs:
Cl2(g)+2KBr(aq)→2KCl(aq)+Br2(aq) \text{Cl}_2\text{(g)} + 2\text{KBr}(\text{aq}) \rightarrow 2\text{KCl}(\text{aq}) + \text{Br}_2(\text{aq}) Cl2(g)+2KBr(aq)→2KCl(aq)+Br2(aq)Explain why this displacement reaction is classified as a redox reaction.
