Solution

The correct option is B False
$A g^{+}$ give yellow precipiate of silver iodide on reaction with $K I$ solution.
$A g^{+} + I^{-} ⟶ A g I ↓ e x c e s s K I - ----- \to Y e l l o w p p t$ No change
The precipitate is insoluble in dilute or concentred ammonia but dissolves in KCN and in sodium thiosulphate.
$A g I ↓ + 2 C N^{-} ⟶ [A g (C N)_{2}]^{-} + I^{-}$
$A g I ↓ + 2 S_{2} O_{3}^{2 -} ⟶ [A g (S_{2} O_{3})_{2}]^{3 -} + I^{-}$
