Abstract

Transition metals have many industrial and research applications. Also, many biological systems have transition metal ions as cofactors. One of the
most extensively studied transition metals is Manganese. Under acidic conditions Mn2+ state is very stable, however, under alkaline condition Mn2+
state is readily oxidized to Mn3+ state. In solution, Mn3+ state disproportionate to Mn2+ state and Mn4+ state. Results from this study show that
oxidation of Mn2+ state to Mn3+ state can take place in the presence or absence of oxygen. Also, the oxidation of Mn2+ state to Mn3+ state is faster in
the oxygen rich environment than in inert environment suggesting different reaction kinetics are involved. Finally, the chemistry of aqueous Mn2+ state under alkaline condition is presented.
