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

(1) 0.1 mol dm-3 AgNO3 solution

(2) 0.1 mol dm-3 HCl solution

(3) H2O

(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, [Ag(NH3)2]+Cl- and complex formation increases the solubilty
