Description of key information
Assumed to decompose completely without boiling
Key value for chemical safety assessment
Additional information
Testing for this endpoint has been waived in accordance with column 2 restrictions.
Dry salts
For dry salts this endpoint has been waived as these materials melt above 300 °C and/or decompose before boiling.
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].
The likely boiling point ranges from ca. 104 to 120 °C at 101325 Pa.
