Precipitation Titration

image of Precipitation Titration

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.
