Introduction
Off-white to beige powder. Astringent. It is mainly composed of FeSO4?H2O, and contains a small amount of FeSO4?4H2O. Difficult to oxidize and easier to store than crystalline ferrous sulfate. The aqueous solution was acidic and turbid, and a yellow-brown precipitate formed gradually. Absorbs water in humid air to form heptahydrate salts. Heated to 120 ℃ without losing water. It can be converted into basic sulfate by boiling with water. It is slowly dissolved in cold water (26.6g/100ml, 20°C), and rapidly dissolved when heated. Insoluble in ethanol. Almost insoluble in 50% sulfuric acid.

● Nutritional supplements (fortification with iron). Use the same as ferric lactate. It is used as a coloring agent for black beans, candied broad beans (addition amount of 0.02% to 0.03%), kelp, etc.
● Other uses are the same as "Ferrous Sulfate (01215)".
It is a blood tonic for raising livestock, which can promote the growth and development of animals, and can also be used to make pigments such as iron oxide re
● It is obtained by drying crystalline ferrous sulfate at 40°C into powder. When heated to 45～50℃, it dissolves in crystal water and liquefies, and slowly evaporates crystal water while stirring. The limit of weight loss on drying is 35% to 36%, and it generates fine powder in the state of small particles, which is made into powder and sealed for storage.
