Metal Halides - Wikipedia
The silver and thallium(I) cations have a great affinity for halide anions in solution, and the metal halide quantitatively precipitates from aqueous solution. This reaction is so reliable that silver nitrate is used to test for the presence and quantity of halide anions. The reaction of silver cations with bromide anions: ... Read Article

EXPERIMENT 4 FAJANS DETERMINATION OF CHLORIDE
We can take advantage of this change in the environment of the analyte solution. It is a general property of ionic precipitates like AgCl to adsorb their own ions from solution. Thus, a silver chloride precipitate standing in a solution containing excess chloride ions causes a layer of chloride ions to adhere to its surface. ... View Document
