pubs.usgs.govratory, and solutions of permanganate have sufficient stability to be used in oxidation-reduction titrations. The oxidizing power of per manganate, however, is great enough to release oxygen froir water, although ordinarily the reaction is very slow. The principal common minerals of manganese are the oxides and
