Description of key information
The water solubility of KBF4 is 5.40 g/L at 22˚C and pH = 3.0
Key value for chemical safety assessment
- Water solubility:
- 5.4 g/L
- at the temperature of:
- 22 °C
Additional information
The water solubility of KBF4 was determined in a GLP-compliant study according to OECD TG 105. The BF4- concentrations (expressed as KBF4) were determined after t = 1, 2, 3, 4, 5, 6, 24, 48 and 72 hours. The water solubility for KBF4 determined at each time point did not differ with more than 10% from the water solubility determined at t = 1 hour, which indicates that KBF4 dissolves to its maximum water solubility within 1 hour. The BF4- concentrations measured after 48- and 72-hour incubation did not differ by more than 15%. Therefore the water solubility test is considered to be satisfactory. The water solubility of KBF4, defined as the average value of the determinations after 24, 48 and 72 hours, is 5.40 g/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
