Miscellaneous Titrations

ARGENTOMETRY

Introduction and Principle

This titrimetric method is mainly based on the titrant used in the titration. The silver nitrate is used as the titrant which precipitates the subsequent halide. This method is similar to that of the precipitation titrations. It is mainly used for the determination of the halides and halide compounds.

 

AgNO3 + HX Image AgX + HNO3

Theory

The sample is mixed with the silver nitrate and forms the precipitate. In argentometric titrations, the sodium chloride is used as the primary standard for the standardisation of the silver nitrate.
