MCQ
Silver chloride dissolves in
  • A
    Water
  • B
    Conc. $HCl$
  • ✓
    $NH_4OH$
  • D
    $CCl_4$
✓

Answer

Correct option: C.
$NH_4OH$
c
$AgCl$ is insoluble in water, conc. $HCl$ and $CCl_4$.

It dissolves in $NH_4OH$ solution due to the formation of complex salt.

$AgCl + 2N{H_4}OH \to \mathop {[Ag{{(N{H_3})}_2}]Cl + 2{H_2}O}\limits_{{\text{Diamminesilver (I) chloride}}} $
