Zinc sulfate (ZnSO4) is white.
Understanding Zinc Sulfate's Appearance
Zinc sulfate is an inorganic compound widely known for its various applications. Its physical appearance is consistently described as a white powder. This characteristic holds true for its anhydrous form as well as its various hydrated forms, such as the monohydrate (ZnSO4·H2O) and the more common heptahydrate (ZnSO4·7H2O), often referred to as white vitriol.
Below is a summary of some key properties of zinc sulfate:
| Property | Description |
|---|---|
| Chemical Formula | ZnSO4 |
| Appearance | white powder |
| Odor | odorless |
| Molar Mass | 161.44 g/mol (anhydrous) |
| 179.47 g/mol (monohydrate) | |
| 287.53 g/mol (heptahydrate) |
The distinctive white color is a fundamental physical property of zinc sulfate, making it easily identifiable among chemical compounds.
