    Before the titration an excess volume of a silver nitrate solution is added to the solution containing chloride ions, forming a precipitate of silver chloride. The term 'excess' is used as the moles of silver nitrate added are known to exceed the moles of sodium chloride present in the sample so that all the chloride ions present will react.

  • Precipitation Titrations - cffet.net

    Precipitation Titrations Precipitation relies on a complete reaction between analyte and precipitating reagent. This is also one of the requirements of a titration reaction. Precipitation reactions are generally slow, involving periods of digestion, cooling, filtration etc. This tends to limit the reactions that are available for titration.
