Agriculture :-Zinc sulphate is a very water soluble, transparent, colourless, crystalline compound. It is commonly used as the heptahydrate, ZnSO4 •7H2O, and is commonly called white vitriol; it occurs naturally as the mineral grossularite, and can be prepared by reacting zinc with sulphuric acid. It is used to supply zinc in animal feeds, fertilizers, and agricultural sprays; in making lithopone; in coagulation baths for rayon; in electrolyte for zinc plating; as a mordant in dyeing; as a preservative for skins and leather; and in medicine as an astringent.
Textile Application: The second major use for zinc sulphate is the manufacture of viscose rayon fibre. Zinc sulphate is one of the ingredients in the spinning bath along with sodium sulphate and sulphuric acid.
Industrial application: Zinc sulphate is the ideal source of zinc for the production of zinc stearate. It is used as a catalyst in numerous chemical operations and in the production of butyl rubber. Zinc Sulphate Solution is used as the source of zinc in the manufacture of zinc dithiocarbamate rubber accelerators.Zinc Sulphate Monohydrate: Zinc Sulphate used in in pharmaceuticals for Zinc deficiency.
