Complexometric titration

Complexometric titration is a method used to determine the concentration of specific metal ions in a solution. It involves adding a chelating agent, like EDTA, that forms stable, colored complexes with metal ions. As the titrant is added, it binds to the metal, and an indicator signals the endpoint when all the metal ions are chelated. This technique is precise for analyzing water hardness, metal content in samples, and other applications where accurate metal ion measurement is needed. It relies on the formation of complex ions to quantify the amount of metal present.
