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

Step 1:
Disproportionation is a chemical reaction, typically a redox reaction, in which a substance is simultaneously oxidized and reduced, giving two different products.

Step 2:

For example,

(i) 2Cu⁺ → Cu²⁺ + Cu

$(i i) 3 M n O_{4}^{2 -} + 4 H^{+} \to 2 M n O_{4}^{2 -} + M n O_{2} + 2 H_{2} O$
$M n (l V) M n (V l l) M n (l V)$

Mn (VI) is oxidized to Mn (VII) and reduced to Mn (IV).
