Ferrous Ammonium Sulphate – 500 gram Packs

Ferrous Ammonium Sulphate, also known as Mohr’s Salt or Ammonium Iron(II) Sulphate, is an inorganic double salt containing ferrous ions, ammonium ions, and sulphate ions. It is commonly supplied as the hexahydrate, with the chemical formula (NH₄)₂Fe(SO₄)₂·6H₂O and a molecular weight of approximately 392.14 g/mol. This compound is valued in analytical chemistry because its iron(II) content makes it suitable for oxidation–reduction titrations and quantitative laboratory investigations. Its light green to blue-green crystalline appearance and relatively good stability under appropriate storage conditions make it a useful reagent for chemistry practicals and research. Ferrous Ammonium Sulphate is used in educational institutions, analytical laboratories, and research facilities for standard solution preparation and iron-related chemical studies. The suitability of this 500 g pack depends on the required grade, assay, and analytical method.
