Precipitation titration is a titration where the precipitation responses occur.

In this method of titration, the titrant responds with the analytes which are framed with

insoluble material and the process of titration starts with devoured analytes. To decide

the convergence of chloride particle in a specific arrangement, we can titrate this

arrangement with silver nitrate. In the principle, the contingent on the upsides of ionic

item, the arrangements can be characterized into three distinct classes where the

precipitations occur. In precipitation titration, generally three methods were studied

including Volhard’s method which was given by Jacob Volhard in 1874. The scientist

planned the technique for assessment of silver particles [AgNO3] in weakening

corrosive arrangements by titrating against a standard thiocyanate arrangement within

the sight of ferric salt Ferric ammonium sulfate as pointer. The second one is the

Mohr’s method which was given by Karl Friedrich Mohr in 1856 who presented it for

the assurance of halide/chloride with silver nitrate utilizing potassium chromate

arrangement as pointer. It is particularly helpful for the assurance of chloride. The third

method is Fajan’s method which was given by Kazimierz Fajan in 1923 in which the

adsorption markers were used. In the measure of substances which respond with nitrate

however this can’t be controlled by direct titration with silver nitrate arrangement and

the greater part of the utilizations of precipitation titrations depend on the utilization of

a standard silver nitrate solution. In this chapter, we studied the basic fundamentals of

precipitation titration along with their principle, methods, limitations and their suitable

application.
