Question

Why is there no indicator for redox titration?

Answer 1

Answer:

Nice question

Explanation:

When used in redox titration, it get reduced into brown coloured Mn2+ ion(In acidic media) at end point and colour change at end point can be detected easily. Since detecting end point is the role of indicator, later is not required in Permanganate titration.

In Short: Redox titrations will involve a reducing and oxidizing agent reacting together, but indicator is normally not used like it is in acid-base titrations. This means that one of the reactants used has to be one with a color difference between its reduced and oxidized form.
