Solution

The correct option is B It reacts with $K C l$ to give $C l_{2}$
a) $2 C u S O_{4} + 4 K I \to 2 C u I + I_{2} + 2 K_{2} S O_{4}$
b) $C u S O_{4} + 2 K C l \to K_{2} S O_{4} + C u C l_{2}$
c) $R C H O (g l u c o s e) + 2 C u (C_{4} H_{4} O_{6})_{2}^{2 -} + 5 O H^{-} \to R C O O^{-} + C u_{2} O + 4 C_{4} H_{4} O_{6}^{2 -} + 3 H_{2} O$
d)
$2 C u S O_{4} ⟶ 2 C u O + 2 S O_{2} + O_{2}$
