The reductive dehydration of iron hydroxide (FeOOH) by iron metal in aqueous solutions of ferrous sulphate was found to occur. These reactions of α, β, γ FeOOH and Fe(OH) 3 · nH 2 O respectively were carried out in 0.01–1 mol iron(II) sulphate solutions and over the temperature range of 80–100°C to produce Fe 3 O 4 in all cases. The reaction rate decreases with increasing Fe 2+ concentration and depends on the total concentration of sulphate anion. The presence of iron(II) chloride has an inhibiting effect.
