Chapter 20, Problem 27QAP

Interpretation Introduction

Interpretation:

The calculation is to be done to show which of the listed cation will disproportionate at standard condition.

Concept introduction:

Disproportionation reaction is a special type of redox reaction in which the reacting species has a special ability to undergo oxidation and reduction simultaneously. It forms two types of compound or species, one with higher oxidation state and another with lower oxidation state.

This tendency is better understood with the help of Latimar diagram.

If a species has a higher potential (i.e., more positive) on the right side of Latimar diagram than on the left side, then the species can show disproportionation.
