Product Description
Product name: Ferrous Sulfate Heptahydrate
Chemical Formula: FeSO4.7H2O
Cas: 7782-63-0
Description: Ferrous sulfate has the chemical formula FeSO4. Its prevalent hydrate, FeSO4·7H2O, is popularly called green vitriol. Presenting as a light blue - green monoclinic crystal, in dry air, it undergoes efflorescence. When exposed to moist air, it is highly susceptible to oxidation, with a brown - yellow basic ferric sulfate layer forming on its surface. Ferrous sulfate dissolves readily in water, and the resulting aqueous solution is light - green in color and exhibits a slightly acidic nature.

Application
During the pigment manufacturing process, ferrous sulfate engages in a succession of chemical reactions including oxidation and hydrolysis, which leads to the formation of the corresponding iron oxide pigments. These iron-based pigments possess excellent coloring ability, hiding power, and weather resistance. As a result, they are extensively applied in various industries like architectural coatings, automotive coatings, plastics, and rubber for the purpose of coloring products.
Industrial - grade ferrous sulfate is highly significant in water treatment procedures. Once dissolved in water, hydrolysis occurs, generating a ferrous hydroxide colloid that exhibits robust adsorption capabilities. For instance, when dealing with natural water or industrial wastewater laden with sediment and suspended particles, this ferrous hydroxide colloid is able to adsorb the suspended impurities present in the water. It causes these impurities to aggregate and then settle, thereby fulfilling the objective of purifying the water quality.
In the printing and dyeing industry, ferrous sulfate is employed as a mordant. It is capable of binding with dye molecules, thereby enabling dyes to adhere more effectively to fabric fibers. This action not only heightens the dyeing effect but also ensures that the dyeing is more durable and evenly distributed. For example, during the dyeing of cotton fabrics, soaking the cotton fabrics in a ferrous sulfate solution prior to dyeing can increase the rate at which the fabric absorbs the dye and enhance the color fastness.
