The pink color of acidified permanganate is decolorized and a yellow-orange toluene layer is obtained Q: Give the correct formula of the ion that shows the following results
If the pink colur permangonate is decolurized that means the permanganate is reduced to `Mn^(2+)` .
The yellow -orange toluene layer is obtained when `Br_2` is added to a non-polar solution like toluene.
So Br should be oxidized when permanganate was added.
Therefore the ion is `Br^-`
