Argentometric (silver nitrate) titrations overview
Methods based on precipitation of silver compounds are called collectively argentometric methods. They are most often used for determination of chloride ions, but they can be used also for other halides (bromide, iodide) and some pseudohalides (thiocyanate).
It is also possible to use indirect argentometric methods for determination of anions, that create insoluble salts with Ag+ (for example phosphate PO43-, arsenate AsO43- and chromate CrO42-). These methods are based on back titration of excess silver with standardized thiocyanate solution.
