Ferrous sulfate heptahydrate Usage And Synthesis
Solubility in water (g/100mL)Dissolved grams in 100 mL water at different temperatures (°C):
28.8g/0℃: 40g/10℃;48g/20℃;60g/30℃;73.3g/40℃
101g/60℃: 79.9g/70℃;68.3g/80℃;57.8g/90℃
Chemical propertiesBlue-green crystals (monoclinic system) or granules, odorless. Soluble in water, slightly soluble in alcohol, soluble in anhydrous methanol.
ApplicationsAs analytical reagent; as raw material for ferrite; raw material to produce magnetic iron oxide, iron(III) oxide and iron blue inorganic pigment, iron catalyst and poly iron sulfate; as chromatographic reagent. In agriculture, it is used as pesticide in agriculture to control wheat smut, scab of apple and bear, fruit tree decay; as fertilizer to remove moss and lichen of food trunk. Medically it is used as local astringent, blood tonic and anti-anemia.  Ferrous sulfate heptahydrate (feed grade) can be used as the iron fortifier for feed additive. Ferrous sulfate heptahydrate (food grade) is used as nutrition supplements, such as iron fortifier, coloring agent for fruit and vegetable. According to Chinese regulation, it can be used in following foods and with allowed amounts:
Sweets with filling and salt: 3000~6000 mg/kg;
Cereals with high iron content and corresponding products (maximum daily consumption 50g): 860~960 mg/kg;
Dairy and infant foods: 300-500 mg/kg;
Cereals and corresponding products: 120~140 mg/kg;
Beverages: 50~100 mg/kg. It is used to produce iron salt, iron oxide pigment, mordant, water purifier, preservatives, disinfectant, etc.
Preparation
  • By-product Method: byproduct of titanium dioxide production:
Titanite is decomposed with sulfuric acid to obtain titanium dioxide, ferrous sulfate(II) and ferric sulfate (III). Iron (III) compounds are reduced to obtain iron (II) compounds. The mixture is then cooled and crystallized to form ferrous sulfate.
5H2SO4+2FeTiO3→2FeSO4+TiOS04+Ti(SO4)2+5H2O

  • Sulfuric acid method
Scrap iron is dissolved with a mixture of diluted sulfuric acid solution and mother solution. The reaction temperature should be below 80°C, otherwise, it results in the sedimentation of ferrous sulfate monohydrate. Clarification is applied to remove impurities from the slightly acidic ferrous sulfate solution. Cooling and centrifugation are carried out obtain light-green ferrous sulfate.
Fe+H2SO4→FeSO4+H2↑
