Water Treatment High Purity Ferrous Sulfate Heptahydrate Fertilizer CAS 7782-63-0 With Easy Solubility

Factory supply high-purity ferrous sulfate heptahydrate fertilizer CAS 7782-63-0 for water treatment applications.

Ferrous sulfate is an inorganic compound with the chemical formula FeSO₄. It appears as a white powder and is odorless. Its crystalline hydrate is the heptahydrate at room temperature, commonly known as "green vitriol," which is a light green crystal. It effloresces in dry air and oxidizes on the surface to form a brown basic iron sulfate in moist air.

At 56.6℃, it becomes the tetrahydrate, and at 65℃, it becomes the monohydrate. Ferrous sulfate is soluble in water and almost insoluble in ethanol. Its aqueous solution oxidizes slowly in air when cold and more rapidly when hot. The oxidation process can be accelerated by the addition of alkali or exposure to light. Its relative density (d15) is 1.897.
