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. 7446-20-0 (heptahydrate) Bonazen Bufopto zinc sulfate Complexonat Kreatol Medizinc Neozin Nu-z Op-thal-zin Optised Optraex Orazinc Prefrin-z Solvazinc Solvezinc Solvezink Sulfate de zinc Sulfate, zinc Sulfuric acid zinc salt Sulfuric acid zinc salt (1:1) Sulfuric acid zinc salt (van) Sulfuric acid, zinc salt Sulfuric acid, zinc salt (1:1) Sulfuric acid, zinc salt(1:1) Verazinc Visine-ac White copperas White vitriol White vitriol (van) Z-span Zinc sulfate (1:1) Zinc sulfate (ZnSO4) Zinc sulfate [usp] Zinc sulfate anhydrous Zinc sulfate, heptahydrate Zinc sulphate Zinc vitriol Zinc vitriol (van) zinc(2+) sulfate Zinc(II) sulfate Zincaps Zincate Zinci sulfas Zincomed Zincosite Zincteral Zink-gro Zinklet Zinkosite ZnSO4 O4SZn 161.472 159.880875756 zinc(2+) ion sulfate zinc(2+) ion sulfate 7733-02-0 [Zn++].[O-]S([O-])(=O)=O InChI=1S/H2O4S.Zn/c1-5(2,3)4;/h(H2,1,2,3,4);/q;+2/p-2 NWONKYPBYAMBJT-UHFFFAOYSA-L belongs to the class of inorganic compounds known as transition metal sulfates. These are inorganic compounds in which the largest oxoanion is sulfate, and in which the heaviest atom not in an oxoanion is a transition metal.
