Ferrous sulfate is an inorganic substance with the chemical formula FeSO4 and a white powder with no odor. Its crystal hydrate is heptahydrate at room temperature, commonly known as "green alum", light green crystals, weathered in dry air, oxidized to brown basic iron sulfate on the surface in humid air, becoming tetrahydrate at 56.6 °C, and monohydrate at 65 °C. Ferrous sulfate is soluble in water and almost insoluble in ethanol. Its aqueous solution oxidizes slowly in the air when it is cold and oxidizes quickly when it is hot. The addition of alkali or dew can accelerate its oxidation. Relative density (d15) 1.897. It is irritating. Ferrous sulfate can be used as a chromatographic analysis reagent, drip analysis for the determination of platinum, selenium, nitrite and nitrate. Ferrous sulfate can also be used as a reducing agent, to make ferrites, to purify water, to polymerize catalysts, photographic plates, etc.
