     [1913 Webster]

  chelate \che"late\, n. (Chem.)
     a compound formed by combination of a metal ion in solution
     with a compound containing heteroatoms (such as oxygen or
     nitrogen), in which at least two heteroatoms are bound to the
     metal. The bonds may be covalent or non-covalent. Chelates in
     some cases have very low dissociation constants, and organic
     compounds (chelating agents) which form such chelates are
     therefore used to reduce the concentration of free metal ions
     in solution.
