Manganese is a pinkinsh-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids. Applications. Manganese is essential to iron and steel production.

The effects of exposure to any hazardous substance depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other chemicals are present. For more information, call the ATSDR Information Center at 1-800-232-4636. This public health statement tells you about manganese and the effects of exposure to it.
Characteristics: Manganese is a gray-white, hard, brittle, metal that can take a high polish. It is not magnetic. The metal tarnishes on exposure to air and, when heated, oxidizes to manganese (II, III) oxide (Mn 3 O 4 ). Like other transition metals, manganese has more than one common oxidation state.
