Zinc Sulphate is Inorganic compound. Zinc Sulphate can be offered in two different grades i.e. Zinc Sulphate Heptahydrate & Zinc Sulphate Monohydrate. Zinc Sulphate is freely soluble in water. Zinc Sulphate is incompatible with strong oxidising agents. Zinc is a naturally found in the earths crust and is an inherent part of our environment. Zinc is present not only in rock and soil, but also in air, water and the biosphere. Plants, animals and humans contain zinc in their bodies. The average natural level of zinc in the earths crust is 70 mg/kg (dry weight), ranging between 10 and 300 mg/kg (Malle 1992). In some areas, zinc has been concentrated to much higher levels by natural geological and geochemical processes (5-15% or 50,000-150,000 mg/kg). Such concentrations, found at the earths surface and underground, are being exploited as ore bodies Centuries ago zinc was discovered in the metallic form, its ores were used for making brass and zinc compounds and also for healing wounds and sore eyes. It is believed that the Romans first made brass in the time of Augustus (20 B.C. 14 A.D.). In the 13th century Marco Polo described the manufacture of zinc oxide in Persia. By 1374, zinc was recognized in India as a new metal the 8th metal known to man at that time. At Zawar in India, both zinc metal and zinc oxide were produced from the 12th to the 16th century. Zinc metal was used to make brass, and zinc oxide served medical purposes. Zinc Sulphate has an application in Pharmaceutical & Cosmetic Industry as a source on Zinc in the formulation. Zinc Sulphate is also used in Agriculture for fortification purposes. Zinc Sulphate is also used in Zinc plating (Metal Treatment Industry) & as a mordant in dyeing.
