Precipitation Titration and its Type

 Precipitation Titration

The titration in which reaction between titrate and titrant results in the formation of precipitates or slightly soluble ionogens is called precipitation titration.

Here the coloured particles floating in the solution is
known as precipitates (ppt.) 

 Types of Precipitation Titration

There are basically two types of Precipitation titration:

1. Argentometric Titrations:-

---> The titration in which AgNO3 is used as titrant is called argentometric titration.

2. Mercurometric Titrations:-

---> When mercuric Nitrate is used as titrant, the titration is called mercurometric titration.

---> It can be used for the estimation of halides (chloride / bromide), thiocynate etc.

---> in this titration, the end point is not clear, so ethanolic medium is used for the titrations. Diphenly carbazone is used as an indicator which imparts blue color at the end of the titration.
