Solution

The correct option is D Caustic potash solution
Hydrogen gas prepared in laboratory contains impurities like $S O_{2}$ , $C O_{2}$ and $N O_{2}$ as impurities. Sulphur dioxide can be removed by passing it through the caustic potash solution. $S O_{2} (g) + 2 K O H (a q) ⟶ K_{2} S O_{3} (a q) + H_{2} O (l)$
