Question #c9a04

Answer 1

Permanganate anion is usually oxidized to COLOURLESS `Mn^(2+)`

Explanation:

And we would represent this reaction by the 5 electron reduction.....

`underbrace(MnO_4^(-))_"deep purple" + 8H^+ + 5e^(-) rarr Mn^(2+) + 4H_2O`

VERY concentrated solutions of `Mn^(2+)` are a pale rose.

You will have to supply a corresponding oxidation reaction.
