Manganese(II) hydroxide
Manganese hydroxide is the inorganic compound with the formula Mn2. It is a white solid although samples darken quickly upon exposure to air owing to oxidation. It is poorly soluble in water.Manganese hydroxide precipitates as a solid when an alkali metal hydroxide is added to an aqueous solution of Mn2+ salt:
Manganese hydroxide oxidises readily in air, as indicated by darkening of samples.
The compound adopts the brucite structure, as do several other metal dihydroxides.
