Description of key information
Anhydrous form
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 1 023 °C
Additional information
Testing for this endpoint has been waived in accordance with column 2 restrictions.
Aqueous solutions
The boiling point of watery iron salt solutions can be approximated based on the molarity by:
delta T(boiling) = bs∙Ke,
where delta T(boiling) is the boiling point elevation [K], Ke is the ebullioscopic constant for water (= 0.521 K∙kg/mol) and bs is the combined molarity of the salts [mol/kg].
