If the following preparations are carried out. "Potassium permanganate from manganese dioxide".

Balanced reaction is given by : $2 M n O_{2} + 4 K O H + O_{2} \to 2 K_{2} M n O_{4} + 2 H_{2} O$
$2 K_{2} M n O_{4} + {C l}_{2} \to 2 K M n O_{4} + 2 K C l$ .
If the given statement is true enter 1 else 0.

Solution

The MnO2 is fused with potassium hydroxide and heated in air or with another source of oxygen, like potassium nitrate or potassium chlorate. This process gives potassium manganate.

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

The potassium manganate is then be converted into permanganate by electrolytic oxidation in alkaline media:
$2 K_{2} M n O_{4} + {C l}_{2} \to 2 K M n O_{4} + 2 K C l$
So, the correct answer is 1
