Chelate titration

WebIn a complexometric titration, a solution containing the free metal ion of interest is titrated with a solution of a chelating agent until all of the metal ions are bound. The endpoint is usually signaled by an indicator ligand that forms a colored complex with the free metal ion. Figure 2 EDTA – a chelate used by industry and analytical chemists WebThe change in titration curve depends also on the concentration of sample and titrant solution analogously to other titration types. The most common indicators in complexometric titrations are organic dyes which function by forming a colored complex …
