Answer:

Solution:

It reduces and hence, decolourises acidified $K M n O_{4}$ solution.
$2 K M n O_{4} + 3 H_{2} S O_{4} + 10 H I \to K_{2} S O_{4} + 2 M n S O_{4} + 8 H_{2} O + 5 I_{2}$
A. $H_{2} S O_{4} + 2 H I \to S O_{2} + I_{2} + 2 H_{2} O$
B. $H I O_{3} + 5 H I \to 3 I_{2} + 3 H_{2} O$
D. $2 C u S O_{4} + 4 H I \to 2 C u I_{2} + 2 H_{2} S O_{4}$
$2 C u I_{2} \to C u_{2} I_{2} + I_{2}$
