Description of key information
Relative densities are
FeSO4: Anhydrous 3.7; Monohydrate 3.0; solution (20 %) 1.2
Key value for chemical safety assessment
Additional information
A number of densities, relative densities and bulk densities are available from the literature for different hydration states.
Table: Relative densities or densities [g/cm³] under standard pressure (ISO 5011, i.e. 101.3 kPa)
| Category member, Molecular Formula | Anhydrous form | Solid hydrate form | Aqueous solution |
| Ferrous sulphate, FeSO4 | 3.65 at ambient temperature | Monohydrate (CAS 17375-41-6): 3.0 at ambient temperature | 1.21 at 18 °C, 20 % |
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
