An aqueous solution contains a mixture of chloride, bromide, and iodide ions.
An excess of AgNO3(aq)\text{AgNO}_3(\text{aq})AgNO3(aq) is added to this mixture, followed by an excess of dilute NH3(aq)\text{NH}_3(\text{aq})NH3(aq).
The resulting mixture is then filtered.
Which compound(s) is/are present in the residue on the filter paper?
AgI\text{AgI}AgI only
AgBr\text{AgBr}AgBr and AgI\text{AgI}AgI
AgCl\text{AgCl}AgCl and AgBr\text{AgBr}AgBr
AgCl\text{AgCl}AgCl only
