Article: Zinc sulfate

Zinc sulfate (ZnSO₄) 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 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.

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 as it is moss.
