Zinc Sulphate Monohydrate vs. Zinc Sulphate Heptahydrate: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 26, 2024
Zinc sulphate monohydrate contains one water molecule, while zinc sulphate heptahydrate has seven, affecting their water content, solubility, and applications.

Key Differences

Zinc sulphate monohydrate, ZnSO4·H2O, has one water molecule as part of its crystal structure. In contrast, zinc sulphate heptahydrate, ZnSO4·7H2O, contains seven water molecules. This difference in water content significantly influences their physical properties, such as density and crystal form.
