Chemical properties: ferrous sulfate is easy to form hexahydrated double salt m2fe (SO4) 2 · 6H2O with alkali metal sulfate (including ammonium salt), in which m is alkali metal ion or ammonium ion. Ferrous double salts are much more stable, such as ammonium ferrous sulfate (NH4) 2Fe (SO4) 2 · 6H2O, also known as Moore salt, which is a common reducing reagent in analytical chemistry. It is soluble in water and glycerol and has certain reducibility.
Uses: ferrous sulfate is an inorganic metal salt, which can be used as a nutritional supplement (iron fortifier); Fruit and vegetable colorant; It can also be used to make iron salt, iron oxide pigment, mordant, water purifying agent, preservative, disinfectant, etc. in medicine, it can be used as anti anemia medicine.
