when acidified potassium permanganate is mixed with a reducing agent, what will be the observation?

The purple potassium permanganate solution is decolorized when acidified potassium permanganate is mixed with a reducing agent.

Acidified potassium permanganate is a strong reducing agent. When it is mixed with a reducing agent, the acidified potassium permanganate solution is reduced to manganese(II) solution, which is a pale pink solution. However, the manganese(II) solution is very dilute, as the potassium permanganate solution used in this way is always very dilute. Hence, the manganese(II) solution looks colorless.

potassium permanganate is purple
When it is reduced it turns green then if further reduced it turns into a black precipitate
MnO4- -> MnO4 2- -> MnO2
