What is meant by ‘disproportionation’? Give two examples of disproportionation reaction in aqueous solution.

Explanation

Disproportionation reactions are those in which the same substance undergoes oxidation as well as reduction, i.e., oxidation number of an element increases as well decreases to form two different products.
e.g., `(overset(+)(3MnO)_4^(2-)+4H^(p+)tooverset(+7)(2MnO)_4^(ɵ)+overset(+4)(MnO_2)+2H_2O)`
