On standing, oxidation causes the iron (II) hydroxide to turn brown-yellow colour due to gradual formation of iron(III) hydroxide. Fe 2+ (aq) + 2OH – (aq) → Fe(OH) 2 (s)
Reactions of the Hexaaqua Ions with Hydroxide Ions
Iron(II) hydroxide or ferrous hydroxide is an inorganic compound with the formula Fe(OH)2. It is produced when iron(II) salts, from a compound such as iron(II) sulfate, are treated with hydroxide ions. Iron(II) hydroxide is a white solid, but even traces of oxygen impart a greenish tinge. The air-oxidised solid is … See more Iron(II) hydroxide is poorly soluble in water (1.43 × 10 g/L), or 1.59 × 10 mol/L. It precipitates from the reaction of iron(II) and hydroxide salts: FeSO4 + 2 NaOH → Fe(OH)2 + Na2SO4 If the solution is not See more 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. This process is described by the Schikorr reaction: 3 Fe(OH)2 → Fe3O4 … See more Iron(II) hydroxide has also been investigated as an agent for the removal of toxic selenate and selenite ions from water systems such as wetlands. The iron(II) hydroxide See more Fe(OH)2 is a layer double hydroxide (LDH) easily accommodating in its crystal lattice ferric ions (Fe ) produced by oxidation of ferrous ions (Fe ) by … See more Iron dissolved in groundwater is in the reduced iron II form. If this groundwater comes in contact with oxygen at the surface, e.g. in natural springs, iron II is oxidised to iron III and forms insoluble hydroxides in water.
