Assertion (A) In the reaction between potassium permanganate and potassium iodide, permanganate ions acts as oxidising agent.
Reason ( R) Oxidation state of manganese changes from +2 and +7 during the reaction.

A

Both A and R are true and R is the correct explanation of A

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is flase

D

Both A and R are false

Text Solution

Verified by Experts

Correct explanation. The ionic equation involved in the reation is
`overset(+7)2MnO_(4)^(-)+6I^(-)+4H_(2)Orarr3I_(2)+2overset(+4)MnO_(2)+8OH^(-)`
Oxidation state of Mn decreases from +7 to +4
