Several hydrates of Iron(III) oxide exist. When alkali is added to solutions of soluble Fe(III) salts, a red-brown gelatinous precipitate forms. This is not Fe(OH)3, but Fe2O3·H2O (also written as Fe(O)OH). Several forms of the hydrated oxide of Fe(III) exist as well. The red lepidocrocite (γ-Fe(O)OH) occurs on the outside of rusticles, and the orange goethite (α-Fe(O)OH) occurs internally in rusticles. When Fe2O3·H2O is heated, it loses its water of hydration. Further heating at 1670 ke… WebJun 6, 2016 · Iron oxide red is an inorganic synthetic component obtained from iron(II) sulfate by the Penniman–Zoph method. Iron oxide red is an orange-red to violet-red powder with a relative and apparent density of approximately 5.0 kg/L and 0.7 kg/L, respectively. It is insoluble in water and organic solvents, and soluble in mineral acids.
