Description of key information

Relative density data are
FeClSO4: Dry salt not stable; solution (40 %) 1.5

Key value for chemical safety assessment

Additional information

This endpoint has been waived as measurement of the dry salt is technically not feasible. The compound is marketed as aqueous solution only.
