Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Terbium trinitrate was determined to be very soluble in water with a maximum solubility between 1451 g/l and 1475 g/l, at 19.9 - 21.5°C and pH = ca. 0 (-1.11 to -1.07). It is important to note that the solubility was significantly decreased (i.e. 952 g/L) when the pH was adjusted to ca. 5. At higher pH values (i.e. from at least 7.19), terbium trinitrate is entirely precipitated.

Key value for chemical safety assessment

Water solubility:
1 451 g/L
at the temperature of:
19.9 °C

Additional information

An experimental study of reliability 1 according to Klimisch, performed in compliance with GLP and according to the preliminary test as specified in EU method A.6 and OECD Guideline 105, was selected as a key study.
