Manganese sulfate

Description

A pale pink, granular, odorless powder. It is freely soluble in water and is insoluble in alcohol.

Chemical properties

Translucent, pale-rose-red, efflorescent prisms. Soluble in water; insoluble in alcohol.

The Uses of Manganese sulfate

Supplement (trace mineral).

Definition

ChEBI: A metal sulfate in which the metal component is manganese in the +2 oxidation state.
Also known as manganous sulfate, MnS04,4H20 is water-soluble, translucent, efflorescent rose-red prisms which melt at 30°C. It is used in medicine,textile printing,and ceramics,as a fungicide and fertilizer, and in paint manufacture.

Safety Profile

Poison by intraperitoneal route. Questionable carcinogen with experimental neoplas tigenic data. An experimental teratogen. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of SO2, so3, and Mn oxides. See also MANGANESE COMPOUNDS and SULFATES.

Synthesis

In the laboratory, manganese sulfate can be prepared by reacting manganese dioxide with sulfur dioxide. It can also be produced by mixing potassium permanganate with sodium bisulfate and hydrogen peroxide. Manganese sulfate is a by-product of several industrially significant oxidation reactions that utilize MnO2, including the production of hydroquinone and anisaldehyde.
