What are the difficulties encountered in precipitation titration
Mumz [18]

One difficulty encountered in precipitation titration is that it is hard to determine the exact end point of its reaction.

Precipitation titration is a titration in which a  reaction  occurs from the  analyte and titrant  to form an insoluble precipitate.

With the use of silver for the titrations, (argentometric) we are able to develop many precipitation reactions.  

The  precipitation titrimetry  methods with the use of argentometry includes  

• Mohr’s Method

• Fajan’s Method

• Volhard’s Method

Difficulties encountered in precipitation titration includes

  • Getting the exact end point is hard.

  • it is a very slow titration method.

  • it includes periods of filtration and cooling thereby reducing the reactions available for this type of titration.
