In other words, a chelating agent is a multidentate ligand. An example of a simple chelating agent is ethylenediamine.ethylenediamine. A single molecule of ethylenediamine can form two bonds to a transition-metal ion such as nickel(II), Ni 2+ .n other words, a chelating agent is a multidentate ligand.
