As a mineral, ZnSO 4 •7H 2 O is known as goslarite. Zinc sulfate occurs as several other minor minerals, such as zincmelanterite, (Zn,Cu,Fe)SO 4 ·7H 2 O (structurally different from goslarite). Lower hydrates of zinc sulfate are rarely found in nature: (Zn,Fe)SO 4 ·6H 2 O (bianchite), (Zn,Mg)SO 4 ·4H 2 O (boyleite), and (Zn,Mn)SO 4 ·H 2 O .
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 ...

Water of crystallization. In chemistry, water (s) of crystallization or water (s) of hydration are water molecules that are present inside crystals. Water is often incorporated in the formation of crystals from aqueous solutions. [ 1 ] In some contexts, water of crystallization is the total mass of water in a substance at a given temperature ...
