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.
