Ferrous sulfate heptahydrate is green in color, monoclinic or granular, and odorless.
Relative density 1.898, melting point 64°C. It is readily soluble in water (48.6 g/100 ml water). It decomposes red-hot at 50°C to form ferric oxide. It is soluble in glycerol, is corrosive, and weathers in dry air. At 56.6°C, the heptahydrate converts to a tetrahydrate, and at 64.6°C, it becomes a monohydrate. At 90°C, six waters of crystallization are lost, and at 300°C, all waters of crystallization are lost, forming an anhydrous substance. Upon red-hot heating, SO₂ and SO₃ decompose and release SO₃. It is corrosive and fluoresces in dry air. The anhydrous substance is a white powder, but turns bluish-green when mixed with water.

Overview
Ferric sulfate easily oxidizes to yellow or rust in humid air. When dissolved in water, the concentration of ferrous sulfate solution is approximately 10%. As a coagulant, ferrous sulfate produces large particles, exhibits good hydrophobicity, settles quickly, and exhibits excellent decolorization. Ferrous sulfate treatment agents are low-cost and suitable for treating wastewater with a pH above 8.5.
Product Application
Water treatment:Ferrous sulfate is used for flocculation and purification ofwater and removal of phosphate from urban and industriasewage to prevent eutrophication of water body.
Reducing agent:A large amount of ferrous sulfate is used as reducing agentmainly reducing chromate in cement.
Medical:Ferrous sulfate is used to treat iron deficiency anemia; lt isalso used to add iron to food.In medicine, it can also beused as a local astringent and blood tonic. lt can be usedfor chronic blood loss caused by hysteromyoma.
Colorant: Ferrous sulfate is used in the production of iron tannateink and other inks. The mordant used for wood dyeing alsocontains ferrous sulfate.b. Ferrous sulfate can be used to dye concrete yellow rust.c.Carpenters use ferrous sulfate to dye Maple with silvelcolor.
Agriculture:Regulating soil pH, promoting the formation of chlorophyll(also known as iron fertilizer), can prevent and control thechlorosis of flowers and trees caused by iron deficiency. lt isan indispensable element of acid loving flowers and treesespecially iron trees. In agriculture, it can also be used as apesticide to prevent wheat smut, scab of apples and pearsand rot of fruit trees;lt can also be used as fertilizer toremove moss and lichens from tree trunks.
Analytical chemistry:Ferrous sulfate can be used as chromatographic reagent.
Product Features
1. A new, high-quality, and highly efficient iron salt inorganic polymer water purifier, coagulant, and flocculant.
2. Contains 22% active ingredient Fe₃⁺, resulting in excellent coagulation performance, dense alum flocs, and rapid settling. Complete settling takes 5-30 minutes, and the use of auxiliary settling facilities results in even faster settling times.
3. Excellent water solubility, low in insoluble matter and heavy metal content, resulting in excellent water purification and stable effluent quality.
4. Stable performance: Dissolved solution can be stored for extended periods without precipitation, deterioration, or pipe clogging.
5. Excellent decolorization, dehydration, deoiling, and phosphorus removal, as well as heavy metal ion removal, with strong COD and BOD removal capabilities.
6. Effectively prevents the health risks of excessive aluminum ion levels in drinking water caused by aluminum salt water purifiers.
7. Suitable for water with a pH range of 4-11, with a pH of 7-8 being optimal. The pH value after purification exhibits minimal fluctuation, reducing water hardness.
