Under anaerobic conditions, the iron(II) hydroxide can be oxidised by the protons of water to form magnetite (iron(II,III) oxide) and molecular hydrogen. It is also easily formed as a by-product of other reactions, a.o., in the synthesis of siderite, an iron carbonate (FeCO3), if the crystal growth conditions are imperfectly controlled. It precipitates from the reaction of iron(II) and hydroxide salts:[3].

The water solubility of some iron … Naturally occurring iron oxide, iron hydroxide, iron carbide and iron penta carbonyl are water insoluble. Solubility of iron and iron compounds. The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and the pH of the solution. Question: Is Fe(OH)2 ( Iron(II) hydroxide ) Soluble or Insoluble in water ? Iron dissolved in groundwater is in the reduced iron II form. Many iron compounds share this characteristic.
