Question

why is an indicator not necessary in the standardization of kmno4 solution by titration with oxalic acid​

Answer 1

Answer:

Hey Mate.

Here Is Your Answer Below

Explanation:

The titration of potassium permanganate (KMnO4) against oxalic acid (C2H2O4) is an example of redox titration. In close proximity to the endpoint, the action of the indicator is analogous to the other types of visual colour titrations in oxidation-reduction (redox) titrations.
