Question

Why is kmno4 solution said to be self indicator in redox titration?

Answer 1

Answer:

because of its colour and it's properties

Answer 2

Answer:

All the permanganate ions are used up in the reaction, the solution loses its pink colour.

This indicates the end of the reaction and hence potassium permanganate is called a self indicator as it acts as an indicator apart from being one of the reactants.
