Solution

Preparation of Potassium Permanganate,
$3 K_{2} M n O_{4} + 2 C O_{2} ⟶ 2 K M n O_{4} + M n O_{2} + 2 K_{2} C O_{3}$
Potassium Manganate is oxidized to Potassium Permanganate by bubbling $C O_{2}$ or $C l_{2}$ or $O_{3}$ into the former.
Ionic equations of the following reactions:
(i) $K M n O_{4}$ with $F e$ :
${2 M n O_{4}}^{2 -} + 16 H^{+} + 10 F e^{2 +} ⟶ 2 M n^{2 +} + 8 H_{2} O + 10 F e^{3 +}$
(ii) $K M n O_{4}$ with $S O_{2}$ :
${2 M n O_{4}}^{-} + 5 S O_{2} + H_{2} O ⟶ {5 S O_{4}}^{2 -} + 2 M n^{2 +} + 4 H^{+}$
