  • question_answer What will happen when chlorine is passed through an aqueous solution of potassium bromide?


                    The solution will acquire an orange colour due to the vapours of bromine that are evolved. Actually, chlorine is a stronger oxidising agent than bromine and oxidises \[B{{r}^{-}}\] ions (in KBr) to \[B{{r}_{2}}\] and itself is reduced to \[C{{l}^{-}}\] ions. \[2KBr+C{{l}_{2}}\xrightarrow{\,}2KCl+B{{r}_{2}}\]
