Iron III Sulfate Formula

Iron (III) Sulfate formula or the ferric sulfate is an inorganic salt with the formula Fe2(SO4)3. It is yellow in colour and is soluble in water. The molecule is formed of Fe+3 cation and SO4–2 anion. It is found in a wide variety of minerals but mainly it is found in marcasite and pyrite. Mostly, ferric sulfate is extracted from nature but can also be prepared by treating ferrous sulfate with sulfuric acid at elevated temperature. In this article, learn more about the Iron (III) Sulfate formula and its chemical structure along with its properties and uses.
