In which of the following solvents is silver chloride most soluble?

(1)  solution

(2)  solution

(3) ${\mathrm{H}}_{2}\mathrm{O}$

(4) Aqueous ammonia

Hint: Complex formation increases the solubility of compound

Among the given solvent, AgCl is most soluble in aqueous ammonia solution. AgCl react with aqueous ammonia to form a complex, ${\left[\mathrm{Ag}{\left({\mathrm{NH}}_{3}\right)}_{2}\right]}^{+}{\mathrm{Cl}}^{-}$ and complex formation increases the solubilty
