Define complexometric titration

Answer 1

Complexometric titration is a type of volumetric titration that involves the formation of a complex between the analyte and a titrant. It is used to determine the concentration of metal ions in a solution by titrating with a chelating agent that forms a colored complex with the metal ion. The endpoint is detected by a color change, which indicates that all of the metal ions have been complexed. This method is commonly used in analytical chemistry to determine the concentration of metals in various samples.
