Ferrous Sulphate Heptahydrate

Ferrous sulfate heptahydrate (chemical formula FeSO4 7H2O) has many uses in industry and daily life, including:
1.Agricultural fertilizer: Ferrous sulfate heptahydrate can be used as an iron source in soil fertilizer. It provides the iron element needed by plants and promotes the growth and development of plants. At the same time, it can also adjust the pH value of the soil and improve the absorption of other nutrients by plants.
2.Water treatment agent: Ferrous sulfate heptahydrate can be used as a water treatment agent, mainly used to remove harmful substances such as phosphorus and sulfide in water. It can purify water quality, prevent eutrophication of water body and prevent corrosion of pipelines and equipment.
3.Medicines and health care products: Ferrous sulfate heptahydrate is used as an iron supplement in medicine and health care products. It is used to treat iron deficiency anemia and to increase hemoglobin levels.
4.Pigments and dyes: Ferrous sulfate heptahydrate can be used to prepare various pigments and dyes. For example, it can be used to prepare iron blue pigments and black dyes.
5.Educational experiments: Ferrous sulfate heptahydrate is often used in chemical experiments and teaching to demonstrate reduction reactions, generate precipitates, and observe its color changes.

NOTE: It should be noted that when using ferrous sulfate heptahydrate, relevant safety operating procedures should be followed, such as wearing protective gloves and glasses, and avoid inhaling its dust or contacting the skin. When used in medicine, it should be used according to the doctor's or manufacturer's advice.
