The silver ion forms a complex with NH3, the demine silver ion,[Ag(NH3)2]+, which is freely soluble in water. Explain in terms of the dissolution equilibrium for AgBr and Le Chatter's principle, discuss how the formation of this ion explains the fact that silver bromide is soluble in concentrated NH3(aq). Given that the solubility product of AgBr is 5.0x10-13.Calculate the molar solubility of Ag Br and the solubility in grams per 100 ml of solution. Would you normally class AgBr as soluble?
