Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): very soluble (> 10000 mg/L)
In this peer-reviewed database, sodium fluoride is reported to have a water solubility on average around 37.03 g/L at 0 °C, 41.4g/L at 20 °C, 39.06 g/L at 25 °C and 41.04 g/L at 40 °C. - Executive summary:
In this peer-reviewed database, sodium fluoride is reported to have a water solubility on average around 37.03 g/L at 0 °C, 41.4g/L at 20 °C, 39.06 g/L at 25 °C and 41.04 g/L at 40 °C. The remaining solubilities in water reported in the database were at non environmental temperatures, i.e well below 0°C and far above 80 °C, and were thus not incorporated in this endpoint study record.
According to the ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, the Gmelin database, related to the Beilstein databse should be considered as a peer-reviewed database. Hence, these values are considered as reliable with restrictions and equivalent to data from Handbook.
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.
