Formula

FeSO₄ 7H₂O

Physical properties

Form: blue-green crystalline solid
Stability: Stable, but air and moisture sensitive
Water solubility: moderate
Specific gravity: 1.89

Principal hazards

Iron (II) sulphate is harmful if swallowed.

Safe handling

Wear safety glasses.

Emergency

Eye contact: Immediately flush the eye with water. If irritation persists call for medical help.
