Titration is a method of chemical analysis; for example:

- volumetry

- potentiometric titration

- amperometric titration

- radiometric titration

- Karl Fisher titration

- spectrophotometric titaration

- viscosimetric titration

and other methods

Radiometric titration is "regular" titration, but with the incorporation of a radioactive indicator to monitor the end-point. And that's right from the IUPAC Compendium of Chemical Terminology. If you need an example, use the link provided to a post on the radiometric titration of hexachloro-platinate (IV). It's a bit esoteric, but it will serve to exemplify the idea behind radiometric titration. It's pretty clear that when working with two precipitates (co-precipitation), the analyst would need a way to differentiate them. In the case cited, the application of radioactive cæsium-137 will permit the observer to more quickly and easily find a cutoff point at which to terminate the titration.

types of conductometric titration:

acid base titration

complexometric titration

replacement titration

redox titration

precipitation titration

Direct titration, Indirect titration, back titration, replacement titration and so on
