answered-by-expert Expert Answer
Coordination compounds are used in many qualitative and quantitative chemical analysis. The color reactions given by metal ions with ligands like chelating ligands,due to coordination entities form the basis of the detection and estimation of analysis process. Example of such reagents are: EDTA, DMG etc. Hardness of water is detected by titration with Na2EDTA. The calcium and magnesium ions form stable complex with EDTA.
