Potassium permanganate on heating at 513...

Potassium permanganate on heating at 513 K gives a product which is :

A

Paramagnetic and colourless

B

Diamagnetic and colourless

C

Paramagnetic and green

D

Diamagnetic and green

Text Solution

Verified by Experts

The correct Answer is:
C
`2KMnO_4 underset(200^@C) overset(Delta)to underset("Green")(K_2MnO_4) + underset("Black")(MnO_4) + O_2`
In `K_2MnO_4` , manganese oxidation state is + 6 and hence it has one unpaired `e^(-)`.

Given below are two statements : Statement I : Potassium permanganate on heating at 500K forms potassium manganate. Statement II : Both potasium permanganate and potassium manganate are tetrahedral and paramaganetic in nature. In the light of the above statement, choose the most appropriate answer from the options given below :

Why is potssium permanganate thermally unstable at 513 K.

When ethanol is heated with alkaline potassium permanganate solution it gets converted in to ethanoic acid. In this reaction , alkaline potassium permanganate acts as:

Potassium permanganate works as oxidising agent both in acidic and basic medium. In bot state product obtained by KMnO_(4) is respectively

Potassium permanganate is prepared by fusing pyrolusite with caustic potash in the presence of air or some oxidising agent which gives a green mass. The green mass is then extracted with water and treated with a current of Cl_2 to form potassium permanganate. In the laboratory, it is prepared by oxidising a manganese (II) salt by peroxosulphate. It acts as an oxidising agent in neutral, alkaline or acidic solutions. Give equation and name the product formed when acidified KMnO_4 is added to KI solution.
