Zinc sulfate is a colorless, water-soluble chemical compound that can be prepared by reacting zinc with sulfuric acid or by adding zinc to a copper sulfate solution. It is used to supply zinc in animal feeds, fertilizers, agricultural sprays, making lithopone, in rayon production, for zinc plating electrolytes, as a dye mordant, and in medicine. A zinc sulfate solution can remove moss from roofs by allowing wind to blow away debris, but should not be used on lawns as it also removes grass. It has also been used to deceivesome medical drug examinations.

1. Zinc sulfate ( Zn SO4 ) is a colorless crystalline, water-soluble chemical compound . The hydrated form, ZnSO4·7H2O, the mineral goslarite , was historically known as "white vitriol " and can be prepared by reacting zinc with aqueous sulfuric acid . It may also be prepared by adding solid zinc to a Copper II Sulfate solution. (Zn+CuSO4->ZnSO4+Cu) It is used to supply zinc in animal feeds, fertilizers, and agricultural sprays. ZnSO4·7H2O is used in making lithopone , in coagulation baths for rayon , in electrolytes for zinc plating, as a mordant in dyeing, as a preservative for skins and leather and in medicine as an astringent and emetic . [1] [2] [3] An aqueous solution of zinc sulfate is claimed to be effective at removing moss from roofs. Spraying a mixture on moss will allow the wind to simply blow off the remaining debris, however it is not recommended for use on lawns as it is as effective at removing grass. [4] Zinc sulfate also has reported uses of deceiving medical drug examinations
