Summary

A new UHPLC/MS/MS method was developed to objectively monitor Ruhemann's purple (RP), enhancing the traditional ninhydrin test for food additive analysis. This analytical method supports visual judgment and optimizes test conditions.

Precipitation Titration: Endpoint Detection Methods

In argentometric precipitation titrations, endpoints can be detected visually by the Mohr, Volhard, and Fajans methods. In the Mohr method, adding a soluble chromate indicator gives an initial yellow color to the analyte solution. As the titrant is added, the first excess of silver ions forms a red silver chromate precipitate, marking the endpoint. The solution pH should be maintained at about 8 by adding solid CaCO3.
In the Volhard method, a standard excess of AgNO3 is first added to the...
