Vedclass · Answer

(B) $AgCl$ is a white precipitate that is insoluble in water but dissolves in excess of certain reagents due to the formation of soluble complex ions.$(I)$ In excess $NH_{3(aq)}$,$AgCl$ forms the soluble complex $[Ag(NH_3)_2]Cl$.$(II)$ In excess $Na_2S_2O_3$,$AgCl$ forms the soluble complex $Na_3[Ag(S_2O_3)_2]$.$(III)$ In excess $NaCN$,$AgCl$ forms the soluble complex $Na[Ag(CN)_2]$.Therefore,$AgCl$ dissolves in all three reagents.

$A$ white precipitate of $AgCl$ dissolves in excess of
$(I)$ $NH_{3(aq)}$
$(II)$ $Na_2S_2O_3$
$(III)$ $NaCN$
