Coordination compounds find use in many
qualitative and quantitative chemical analysis
The familiar colour reactions given by metal ions
with a number of ligands (
especially chelating
ligands),
as a result of formation of coordination
entities, form the basis for their detection and
estimation by classical and instrumental methods
of analysis.
Examples
of such reagents include EDTA, DMG
(dimethylglyoxime
), α
–
nitroso
–
β
–
naphthol,
cupron.
