An anion solution gives a white ppt with $\mathrm{AgNO}_{3}$ solution. The ppt. dissolves in dil.
ammonia due to the formation of
  1. $\mathrm{AgNO}_{3}$
  2. $\mathrm{NH}_{4} \mathrm{NO}_{3}$
  3. $\left\lfloor\mathrm{Ag}\left(\mathrm{NH}_{3}ight)_{2}ight] \mathrm{Cl}$
  4. $\left\lfloor\mathrm{Ag}\left(\mathrm{NH}_{3}ight)_{2}ightfloor \mathrm{Br}$

Solution

$\mathrm{AgNO}_{3}+\mathrm{Cl}^{-} ightarrow \mathrm{AgCl}+\mathrm{NO}_{3}^{-}$
$\mathrm{AgCl}+2 \mathrm{NH}_{3} ightarrow\left[\mathrm{Ag}\left(\mathrm{NH}_{3}ight)_{2}ight] \mathrm{Cl}$
