Ferrous sulfate is an inorganic substance, the chemical formula is FeSO4, the appearance is white powder odorless. Its crystalline hydrate is heptahydrate at normal temperature, commonly known as "green alum", light green crystal, which is weathered in dry air and oxidized to brown on the surface of the basic iron sulfate in humid air, becoming tetrahydrate at 56.6ºC and monohydrate at 65ºC. Ferrous sulfate is soluble in water and almost insoluble in ethanol. Its aqueous solution oxidizes slowly in air when it is cold, and oxidizes faster when it is hot. Adding alkali or exposure to light can accelerate its oxidation. The relative density (d15) is 1.897. It's stimulating. Ferrous sulfate can be used as chromatographic reagent and spot analysis for the determination of platinum, selenium, nitrite and nitrate. Ferrous sulfate can also be used as a reducing agent, the manufacture of ferrite, water purification, polymerization catalyst, photographic plate making, etc.
