1.10553.040Manganese(II) sulfate monohydrateAR25kg Characteristic: Appearance and properties:White to light pink fine crystal or powder. Relative density: 2.9500 Melting point(℃): 400 (-H2O) Solubility: soluble
Manganese sulfide, with the chemical formula MnS, has the CAS number 18820-29-6. It appears as a pale pink solid with no odor. The basic structure of manganese sulfide consists of one manganese atom bonded to one sulfur atom. This compound is insoluble in water. Manganese sulfide is conside...
Manganese(II) sulfate also may be produced by the action of sulfur dioxide with manganese dioxide: MnO2 + SO2 → MnSO4 General Description Odorless pale red slightly efflorescent crystals or light pink powder. pH (5% solution) 3.7. Air & Water Reactions Water soluble. Hygroscopic. Reactivit...
It is freely soluble in water, but is insoluble in alcohol. Function: Nutrient.REQUIREMENTS Identification: A 1:10 aqueous solution gives positive tests for Manganese and for Sulfate. Assay: Not less than 98.0% and not more than 102.0% of MnSO4·H2O. Arsenic: Not more than 3 mg/kg. ...
. In relatively oxidized water, the solubility of Mn2+ may be controlled by manganese oxide equilibria, with manganese being converted to the (3+) or (4+) valence state. In extremely reduced water, the fate of manganese tends to be controlled by the formation of the poorly soluble sulfide....

Microbial oxidation of soluble Mn(II) and the subsequent precipitation of insoluble Mn(III) and (IV) oxides and oxyhydroxides are key controls on Mn cycling in natural waters and are primary sources of these reactive solid phases in natural environments. Mn oxides often have high surface-area ...
Mn(II) in its various forms can be almost entirely measured in the acid-soluble fraction with little in the acid-insoluble fraction, and any increase in the acid-insoluble fraction is an indication of oxidized Mn(II). We refer to the ‘acid-soluble fraction’ as Mn(II), and the ‘acid...
Insoluble Matter: Not more than 0.005%. Iron: Not more than 5 mg/kg. Lead: Not more than 4 mg/kg. pH of a 5% Solution: Between 4.0 and 6.0. Substances Not Precipitated by Sulfide: Not more than 0.2%, after ignition. Sulfate: Not more than 0.005%. ...
In sediments, manganese is known to cycle through burial of oxidized manganese below the redox boundary, reductive dissolution of oxidized manganese to dissolved Mn(II), upward diffusion of dissolved Mn(II), and reoxidation of Mn(II) to insoluble Mn(IV) above the redox boundary. In addition,...
