Chemical Description

  • Ferric sulfate (iron sulfate) is the ferric salt of sulfate. It can be used as a mordant in dyeing and used as a coagulant for the treatment of industrial wastes.
  • In the medical field, it can be used as an astringent and styptic. It is a kind of hemostatic agent being capable of controlling or stopping the flow of blood.
  • It is also recommended that ferric sulfate is a good pulpotomy agent in primary teeth with good potential of substituting the formocresol.
  • It can also be used in pigment, and in pickling baths for aluminum and steel. It is generally prepared through the reaction between ferrous sulfate, sulfuric acid and an oxidizing agent such as nitric acid.
  • Ferric Sulfate is a grayish-white powder or yellow lumpy crystals.
  • Yellow crystals or grayish-white powder.(1) slightly soluble in water, (2) very soluble in water. Keep well closed and protected from light. Noncombustible.
  • The anhydrous salt constitutes grayish-white rhombic crystals; hygroscopic; density 3.10 g/cm3; slightly soluble in cold water; decomposes in hot water.
  • The nonahydrate is a yellow hexagonal crystalline substance; refractive index 1.54; density 2.10 g/cm3; hardness 2.5 Mohs; decomposes at 400°C; very soluble in water.
  • Iron(III) Sulfate can be used for water treatment systems.
  • A yellow crystalline solid or a grayish-white powder. The primary hazard is the threat to the environment.
  • Immediate steps should be taken to limit its spread to the environment. Ferric sulfate is used for water purification, and as a soil conditioner.
  • Soluble in water. Hygroscopic in air. Forms acidic aqueous solutions.
  • Ferric Sulfate is a nutrient and dietary supplement that is a source of iron.
  • In preparation of iron alums, other iron salts and pigments; as coagulant in water purification and sewage treatment; in etching aluminum; in pickling stainless steel and copper; as mordant in textile dyeing and calico printing; in soil conditioners; as polymerization catalyst.
  • Ferrous sulfate,also known as ferris pas, green copperas, green vitriol, iron sulfate, and melanterite, is composed of blue green monoclinic crystals.
  • It is soluble in water and is used as a mordant for dyeing wool in the textile industry. Ferrous sulfate is also used as a disinfectant and in the manufacture of ink.
