Manganese(II) hydroxide precipitates as a solid when an alkali metal hydroxide is added to an aqueous solution of Mn 2+ salt: [3] Mn 2+ + 2 NaOH → Mn(OH) 2 + 2 Na + Manganese(II) hydroxide oxidises readily in air, as indicated by darkening of samples. The compound adopts the brucite structure, as do several other metal dihydroxides.
The tables below provides information on the variation of solubility of different ... Manganese(II) hydroxide: Mn(OH) 2: 3.221×10 −4: Manganese(II) nitrate: Mn(NO ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Manganese oxide is any of a variety of manganese oxides and hydroxides. [1] These include Manganese(II) oxide, MnO; Manganese(II,III) oxide, Mn 3 O 4; Manganese(III) oxide, Mn 2 O 3; Manganese dioxide, MnO 2; Manganese(VI) oxide, MnO 3; Manganese(VII) oxide, Mn 2 O 7; Other manganese oxides include Mn 5 O 8, Mn 7 O 12 and Mn 7 O 13.
Magnesium hydroxide is an inorganic compound with the chemical formula Mg(OH) 2. It occurs in nature as the mineral brucite. It is a white solid with low solubility in water (K sp = 5.61 × 10 −12). [5] Magnesium hydroxide is a common component of antacids, such as milk of magnesia.
Manganese(II) sulfate usually refers to the inorganic compound with the formula MnSO 4 ·H 2 O. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260,000 tonnes of manganese(II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds.
