What is Chlorine(g) + Potassium Bromide (aq) ----> ??

Question

I know it's a single replacement, but how can Chlorine go with Bromine? I don't get it...

Answer 1

Cl2(g) + 2KBr(aq) ==> 2KCl(aq) + Br2(l)

Answer 2

Chlorine + potassium bromide --> bromine + potassium chloride

Cl2(g) + 2KBr(aq) --> Br2(l) + 2KCl(aq)

This is a simple displacement as chlorine is more reactive than bromine.

Answer 3

When chlorine gas is bubbled into an aqueous solution of potassium bromide, some of the bromide ions are oxidized to bromine. Some of the bromine molecules combine with bromide ions to form tribromide ion, Br3-.

The chlorine reacts with the bromide to form bromine
