Chlorine gas reacts with potassium bromide solution to form potassium chloride and bromine.
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)
In this reaction, chlorine is reduced.
Explain, using the equation, how you know that chlorine has been reduced.
