Page 104 of the course reader explains that, "Chelating ligands bind cations tightly: EDTA4- ion used to remove metals from solution." What is a chelating ligand and what is its significance?

A chelate is a complex containing a ligand that forms a ring of atoms that includes the central metal atom. This is directly from the course reader on page 104.

A chelate is a closed loop, so it must have at least two ligating atoms.
