Remarks on result:
other: potassium; mean value of 6 samples. std 1.3 g/L, RSD 1.9 %.
Details on results:
concentration of boron, potassium and fluor in the centrifuge clear aquous phase of the samples.
Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The dissolved elemental concentrations for boron, potassium and fluor are 17.0, 66.4 and 31.0 g/L, respectively. All 3 results show that the substances tested is very soluble.

Description of key information

The water solubility for the different constituent elements is 17.0 g/L for boron, 66.4 g/L for potassium and 31.0 g/L for fluor.
The substance is thus very soluble in water.

Key value for chemical safety assessment
