Zn + H 2 SO 4 + 7 H 2 O → ZnSO 4 ·7H 2 O + H 2. Pharmaceutical-grade zinc sulfate is produced by treating high-purity zinc oxide with sulfuric acid: ZnO + H 2 SO 4 + 6 H 2 O → ZnSO 4 ·7H 2 O. In aqueous solution, all forms of zinc sulfate behave identically. These aqueous solutions consist of the metal aquo complex [Zn(H 2 O) 6] 2+ and SO ...

It was described in 1847. Goslarite belongs to the epsomite group which also includes epsomite (MgSO 4 · 7 H 2 O) and morenosite (NiSO 4 · 7 H 2 O). Goslarite is an unstable mineral at the surface and will dehydrate to other minerals like bianchite (ZnSO 4 · 6 H 2 O), boyleite (ZnSO 4 · 4 H 2 O) and gunningite (ZnSO 4 · H 2 O).
Epsomite crystallizes in the orthorhombic system. The normal form is as massive encrustations, while acicular or fibrous crystals are rarely found. It is colorless to white with tints of yellow, green and pink. It is a soft mineral with variable Mohs hardness around 2.0~2.5, and it has a low specific gravity of 1.67.[5]
Zn + H 2 SO 4 → ZnSO 4 + H 2 Cu(OH) 2 + H 2 SO 4 → CuSO 4 + 2 H 2 O CdCO 3 + H 2 SO 4 → CdSO 4 + H 2 O + CO 2. Although written with simple anhydrous formulas, these conversions generally are conducted in the presence of water. Consequently the product sulfates are hydrated, corresponding to zinc sulfate ZnSO 4 ·7H 2 O, copper(II ...
Sodium molybdate (Na 2 MoO 4 · 2H 2 O) 0.25 mg/l; Zinc sulfate (ZnSO 4 ·7H 2 O) 8.6 mg/l; Ethylenediaminetetraacetic acid ferric sodium (FeNaEDTA) 36.70 mg/L;
Some hydrogen-bonding contacts in FeSO 4 ·7H 2 O. This metal aquo complex crystallizes with water of hydration, ... ZnSO 4 (H 2 O) 7 [Zn(H 2 O) 6] one: goslarite [30]
[zn(h 2 o) 6] 2+ ⇌ [zn(h 2 o) 5 (oh)] + + h + Hydrolysis explains why basic salts such as basic zinc acetate and basic zinc carbonate, Zn 3 (OH) 4 (CO 3 )•H 2 O are easy to obtain. The reason for the hydrolysis is the high electrical charge density on the zinc ion, which pulls electrons away from an OH bond of a coordinated water molecule ...
