How will you ...

Question

How will you pure potassium permanganate crystals from its ore, pyrolusite? Give the reaction involve.

Open in App

Solution

The ore is pyrolusite - $M n O_{2}$
Look the given equation,
${3 K}_{2} M n O_{4} + 4 H C l ⟶ 2 K M n O_{4} + M n O_{2} + 2 H_{2} O + 4 K C l$
Fusion of $M n O_{2}$ with $K O H$ and oxidizing agent results in potassium manganate (green mass) which disproportionates to give potassium permanganate.
