what is the precipitation titration? when we used it?
- Dr Dave PLv 71 decade agoFavourite answer
A precipitation titration is a titration in which as you proceed toward the end point, the substance of interest is precipitates out soultion as an insoluble salt: ie.
Ag+(aq,unknown) + Cl-(aq,titrant) --> AgCl(s)
You would use it, when it was your only other option available to find the amount of unknown in the test solution.
You would probably proceed as follows:
1) one quick titration to get a rough estimate of titrate needed
2) 3 or 4 slow titrations to get a precise titrant value.
3) average the result, with std deviation.

Precipitation titration is an Amperometric titration in which the potential of a suitable indicator electrode is measured during the titration.
It is used for determination of chloride by Mohr's Method using Silver nitrate.

Ppt titration is used for such reaction when the titration is not recognised by changing the colours. during the reaction a salt is precipitated as the titration is completed.Source(s): of course chemistry

mostly used for neutralization reactions when the salt is occured the preciptation can ve observed we use indicators to see the pH range
