What will happen when chloride is passed through an aqueous solution of potassium bromide ?

Explanation

The solution will acquire an orange colour due to the vapours of bromine that are evolted. Actually , chlorine is a stronger oxidising agent than bromine and oxidises `Br^(-)`ions (in KBr) to `Br_(2)` and itself is reducted to `Cl^(-)` ions.
`2KBr+Cl_(2) to 2KCl+Br_(2)`
