What is meant by 'disproportionation'? Give an example of disproportionation reaction in aqueous solution.

Text Solution

Verified by Experts

Decomposition of copper (1) salts in water is an example of disproportionation reaction where half of the Cu(I) changes to copper metal and the other half to copper (II).
`2Cu^(+) rarr Cu + Cu^(2+)`
or `3MnO_(4)^(2-) + 4H^(+) rarr 2MnO_(4)^(-) + MnO_2 + 2H_2O`
