Halide ions (Cl-;Br-;I-) can be indentified apart into a solution by using chemical tests in laboratory.
Consider an unknown compound dissolved in diluite nitric acid (HNO3) .
Then silver nitrate (AgNO3) solution is added.A precipitate will be formed if the unknown solution contains halide ions.The precipitates formed will be Silver Chloride (AgCl) ; Silver Bromide (AgBr) ; Silver Iodide (AgI).All the precipitates are similar in colour.So to distinguish between them and to verify the results ammonia solution must be added (NH4OH).
