Metal Coordination - A Key to Oxidative Stability.

  • Horst G. Langer
Conference paper


The oxidation of metal ions can be pH dependent because of kinetic effects as expressed in equation {1}
$$2{A^ + } + {H_2}O + 1/2{O_2} \rightleftharpoons 2{A^{2 + }} + 2O{H^ - }$$
or might be based on a difference in stabilities of various metal complexes as indicated below {2}
$$\begin{array}{*{20}{c}} {{{\left[ {M{{\left( {O{H_2}} \right)}_6}} \right]}^{2 + }}\;is\;more\;stable\;than{{\left[ {M{{\left( {O{H_2}} \right)}_6}} \right]}^{3 + }}} \\ {{{\left[ {M{{\left( {OH} \right)}_6}} \right]}^{3 - }}\;is\;more\;stable\;than\;{{\left[ {M{{\left( {OH} \right)}_6}} \right]}^{4 - }}} \end{array}$$
