Question

Why ponk colour formed at the end point in mno2 volumetric analysis?

Answer 1

✔ But after titration it is MnO2 and there is no such electronic charge transfer..so it it colorless, due to neutralisation reaction and compound formation with the titrand ions(ions of the solution in the burette). KMnO4 is a self indicator i.e changes colour (pink to colourless) at the end point.

Answer 2

It has a ratio of 1:3
