Description of key information
FeClSO4: Anhydrous form not stable; Aqueous solution (40 %) ca. -50 °C
Key value for chemical safety assessment
Additional information
“Sublimation”
It should be noted that all the soluble iron salt category members decompose at elevated temperatures to give toxic gases. This is sometimes noticed as “sublimation”.
Ferric chloride sulphate, FeClSO4
This endpoint has been waived as measurement of the dry salt is technically not feasible. The compound is marketed as aqueous solution for which the melting point is known to be approximately -50 °C.
