Solution

The correct option is D $K M n O_{4} + H_{2} S O_{4} Δ - \to$
(a)
$M n O_{2} + K O H + O_{2} \to K_{2} M n O_{4} + H_{2} O$

(b)
$K M n O_{4} + K O H \to K_{2} M n O_{4} + O_{2} + H_{2} O$

(c)
$K M n O_{4} + K I \to K_{2} M n O_{4} + O_{2}$

(d)
$K M n O_{4} + H_{2} S O_{4} Δ - \to M n S O_{4} + K_{2} S O_{4} + O_{2} + H_{2} O$

Potassium manganate $(K_{2} M n O_{4})$ is a green coloured salt of $M n$ .
