Magnesium sulfate or magnesium sulphate is a chemical compound, a salt with the formula MgSO 4, consisting of magnesium cations Mg 2+ (20.19% by mass) and sulfate anions SO 2− 4.It is a white crystalline solid, soluble in water but not in ethanol.
In the alkaline solution, dissolved oxygen will oxidize manganese(II) ions to the tetravalent state. 2 Mn 2+ (aq) + O 2 (aq) + 4 OH-(aq) → 2 MnO(OH) 2 (s) Mn has been oxidised to 4+, and MnO(OH) 2 appears as a brown precipitate. There is some uncertainty about whether the oxidised manganese is tetravalent or trivalent.

When a salt of a metal ion, with the generic formula MX n, is dissolved in water, it will dissociate into a cation and anions. [citation needed]+ + (aq) signifies that the ion is aquated, with cations having a chemical formula [M(H 2 O) p] q+ and anions whose state of aquation is generally unknown.
Manganese in oxidation state +7 is represented by salts of the intensely purple permanganate anion MnO − 4. Potassium permanganate is a commonly used laboratory reagent because of its oxidizing properties; it is used as a topical medicine (for example, in the treatment of fish diseases). Solutions of potassium permanganate were among the ...
