(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.
| [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. |

| Questions And Answer | Back Directory | [Description]
Manganese sulphate is the manganese salt of sulfate. It is an important precursor for the preparation of other manganese metal (e.g. manganese dioxide used in dry-cell batteries) and other chemical compounds. It is also an essential trace element which can be supplemented to the soils for plants as well as the feed for animals and livestock. It is also a useful trace element for medium of microbes. It can be manufactured through the reaction between manganese dioxide and sulfur dioxide or between potassium permanganate with sodium hydrogen sulfate and hydrogen peroxide.
| [Chemical Properties]
Manganese sulfate ( MnSO4 ) is a pink crystalline solid. It occurs in nature as several mineral forms, jokokuite, pentahydrite, szmikite, and mallardite. It is used in industrial applications such as dyeing, porcelain glazing, and the manufacture of fertilizers and boiling oils.
In biochemistry, manganese is found in various superoxide dismutases. Manganese sulfate is used as a source of manganese ion in biological research, such as in culturing of Bacillus licheniformis and the induction of chromosomal abnormalities in plants. MnSO4 has been utilized to investigate the enzyme dependent glycosylation of endogenous glycoproteins in human skeletal muscle. A protocol that uses MnSO4 in the removal of contaminating genomic DNA in RNA samples for RTPCR has been published.
| [Uses]
Manganese sulfate is used primarily as a fertilizer and as livestock supplement where soils are deficient in manganese, then in some glazes, varnishes, ceramics, and fungicides (EPA, 1984a; HSDB, 1997; Windholz, 1983).
Granular Manganese Sulfate is a granulated manganese fertiliser for dry application to the soil. It is also used as an ingredient in blended fertilisers.
Granular Manganese Sulfate is primarily intended for use in South Australia in planting fertilisers in crops grown on calcareous soils. Manganese deficiency most commonly occurs on alkaline (high pH) soils.
Manganese is quite abundant in the soil. Deficiency occurs because manganese is tied up or fixed in the soil in forms not available for plant uptake, i.e. at high pH, not because the soil is low in manganese.
Manganese applied as fertiliser can be rapidly converted to plant-unavailable forms.
For this reason, it is recommended that manganese be applied as foliar sprays where practicable, rather than to the soil. In horticultural crops, manganese can be applied with routine crop protection sprays.
| [Preparation]
Manganese sulfate is made by reacting sulfuric acid with manganese dioxide.
MnO2 + H2SO4 → MnSO4
It can also be made by mixing potassium permanganate with sodium bisulfate and hydrogen peroxide. | [References]
