Description of key information
Weight of evidence approach:
- Merck (2006): the water solubility is 90 parts in 100 parts water at 0 °C and 400 parts in 100 parts water at 90 °C
- CRC (2008): selenous acid is very soluble
Supportive data:
- GESTIS (2009): the water solubility is 1670 g/L
Key value for chemical safety assessment
Additional information
According to handbook data (Merck index and CRC handbook) selenous acid is very soluble in water. Handbook data considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance". The statements in these two handbooks are supported by the entry in the "GESTIS-database on hazardous substances".
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.
