Description of key information

Ytterbium trinitrate was determined to be very soluble in water with a maximum solubility between 1725g/l to 1763 g/l, at 19.3 to 20°C and pH = ca. 0 (between -1.00 and -0.91). It is important to note that the solubility was significantly decreased (i.e. 91.9 g/L) when the pH was adjusted to ca. 5. At higher pH values (i.e. from at least 7.04), ytterbium trinitrate was considered as entirely precipitated.

Key value for chemical safety assessment

Water solubility:
1 725 g/L
at the temperature of:
20 °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.
