Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- other: Handbook data
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- From a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance".
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Not applicable - Handbook data
- GLP compliance:
- not specified
- Type of method:
- other: no data
- Water solubility:
- 1 060 000 mg/L
- Temp.:
- 25 °C
- Remarks on result:
- other: no pH stated
- Details on results:
- 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". However, no pH value was given in the CRC handbook for the water solubility of dipotassium sulfite.
- Conclusions:
- Interpretation of results: very soluble (> 10000 mg/L)
According to the reference, the water solublity of dipotassium sulfite is 1060000 mg/L at 25 °C. In conclusion the test substance is very soluble. No pH was given.
Reference
No pH value was given but data could be regarded as valid according to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance".
Description of key information
According to the reference, the water solublity of potassium sulfite is 1060 g/L at 25 °C. In conclusion the test substance is highly soluble in water.
Key value for chemical safety assessment
- Water solubility:
- 1 060 g/L
- at the temperature of:
- 25 °C
Additional information
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.
