Ferrous Sulfate heptahydrate

Ferrous sulfate is an inorganic substance with the chemical formula FeSO4. It appears as a white powder with no odor. Its crystalline hydrate is heptahydrate at room temperature, commonly known as "green alum". It is a light green crystal that is weathered in dry air and oxidized to brown basic ferric sulfate on the surface in humid air. It becomes tetrahydrate at 56.6 ℃ and monohydrate at 65 ℃. Ferrous sulfate is soluble in water and almost insoluble in ethanol. Its aqueous solution slowly oxidizes in air when cold and rapidly oxidizes when hot. Adding alkali or exposure to light can accelerate its oxidation. Relative density (d15) 1.897. It is stimulating. Ferrous sulfate can be used as a chromatographic reagent for the determination of platinum, selenium, nitrite, and nitrate in drop analysis. Ferrous sulfate can also be used as a reducing agent, in the production of ferrites, in water purification, as a polymerization catalyst, in photographic plate making, and more.

Used for making iron salt, iron oxide pigment, mordant, water purification agent, preservative, disinfectant, etc., as an anti-anemia drug in medicine
