Applicant's summary and conclusion
- Conclusions:
- In this peer-reviewed database, sodium fluoride is reported to have a density on average around 2.7583g/mL at 20 °C (+/- 2 °C) at atmospheric pressure for three references reviewed and five values reported. The densities range from 2.712 to 2.809 g/mL at 20 °C (+/- 2 °C) at atmospheric pressure.
Considering a water density of 0.999975 g/mL at 4 °C, a mean value of the relative density of sodium fluoride was calculated. It results to a relative density around 2.76 at 20 °C (+/- 2 °C) at atmospheric pressure. - Executive summary:
In this peer-reviewed database, sodium fluoride is reported to have a density on average around 2.7583g/mL at 20 °C (+/- 2 °C) at atmospheric pressure for three references reviewed and five values reported. The densities range from 2.712 to 2.809 g/mL at 20 °C (+/- 2 °C) at atmospheric pressure.
Considering a water density of 0.999975 g/mL at 4 °C, a mean value of the relative density of sodium fluoride was calculated. It results to a relative density around 2.76 at 20 °C (+/- 2 °C) at atmospheric pressure.
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 database 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.
