Description

Ferrous sulfate (alum) molecular formula FeSO4•7H2O An inorganic compound, anhydrous ferrous sulfate is a white powder, soluble in water, the aqueous solution is light green, commonly found in its heptahydrate (green alum). It is mainly used for water purification, photo plate making and treatment of iron deficiency anemia. Ferrous sulfate can cause pollution to water bodies, irritate the human respiratory system and digestive system, and excessive consumption can lead to life-threatening.

Chemical properties
Restorative. Toxic gases are liberated by high heat content. In the laboratory, it can be obtained by reacting a solution of copper sulfate with iron. Weathering occurs in dry air. In humid air, it is easily oxidized into brownish yellow alkaline iron sulfate that is difficult to dissolve in water. The 10% aqueous solution is acidic to litmus (ph value of about 3.7). Heating to 70 ~ 73 °C to lose 3 molecular water, to 80 ~ 123 ° C to lose 6 molecular water, to 156 ° C above the transformation into alkaline iron sulfate. [1]
