Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment

Additional information

Testing for this endpoint has been waived in accordance with Section 2 of REACH Annex XI (testing technically not feasible).

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].
