AgCl is soluble in:

When AgCl precipitate dissolves in ${\mathrm{NH}}_3\left[\mathrm{Ag}{\left({\mathrm{NH}}_3\right)}_2\right]\mathrm{Cl}$  is formed. Due to the complex ion formation $\left[\mathrm{Ag}\right({\mathrm{NH}}_3{)}_2]\mathrm{Cl}$ ,AgCl is soluble in ammonia. The coordinating connection between the molecules of silver and ammonia will be broken by the addition of nitric acid, which will cause the ammonia to react with the nitric acid to create ammonium nitrate and cause the white precipitate of silver chloride to resurface. Hence AgCl is soluble in aqueous ammonia.
