Question

The role of Mn2+ ion during oxidation-reduction titration of KMnO4, by oxalic acid is---
a. catalyst
b. reductant
c. oxidant
d. reactant
​

Answer 1

Answer:

a) catalyst

hope it will be easy

Answer 2

During the oxidation-reduction titration of KMnO4 by oxalic acid, Mn2+ ion is formed as a product. Therefore, Mn2+ ion is not a reactant in this reaction.

Mn2+ ion is actually formed as a result of the oxidation of MnO4- ion, which is the oxidant in this reaction. Mn2+ ion is also an indicator of the endpoint of the titration, as its presence signals the complete oxidation of oxalic acid.

Therefore, the correct answer is: Mn2+ ion is a product formed during the oxidation-reduction titration of KMnO4 by oxalic acid and serves as an indicator of the endpoint of the titration. It is not a reactant, reductant or oxidant.
