$\text{KMnO}_4 + \text{H}_2\text{SO}_4 + \text{H}_2\text{S} \longrightarrow$
Answer
Answer
Equation: $2\mathrm{KMnO_{4}} + 3\mathrm{H_{2}SO_{4}} + 5\mathrm{H_{2}S} \longrightarrow \mathrm{K_{2}SO_{4}} + 2\mathrm{MnSO_{4}} + 5\mathrm{S} + 8\mathrm{H_{2}O}$
Hydrogen sulphide is oxidised to sulphur and the purple permanganate is decolourised.
