Apperance: Blue-green monoclinic crystal or granule.

Nature: Odorless and tasteless. The relative density is 1.89 and the melting point is 64°C. Soluble in water, slightly soluble in alcohol, soluble in anhydrous methanol. When the temperature reaches 56.6°C, three molecules of crystal water are lost; 65 to 90 °C becomes a hydrate; 300°C becomes a white powder of anhydrous matter; temperature to 480°C began to decompose.

Use: Ferrous sulfate can be used as a raw material for the production of water purifying agent and iron oxide pigment, and can also be used as a modifier for alkaline soil. Water treatment grade can be used as water treatment coagulant for drinking water, industrial sewage and wastewater. The ph value is in the range of 5.5~9.6, and the effect of water temperature on the flocculation is small, and the flocculation effect is good, but it is more corrosive. Ferrous sulfate is also a trace element fertilizer, which can accelerate the turning green of rice and sugar beet, neutralize alkaline soil, promote the maturity of farm fertilizers, and improve the growth conditions of plants.

Safety: is a low toxicity product. Ingestion may cause gastrointestinal disorders. Ingestion of children will cause Vomit, hematemesis, liver damage. Staff should be protected. Strictly prevent pollution, sun exposure, rain and moisture during storage and transportation.
