Water solubility of ammonium thiosulfate: very soluble
Key value for chemical safety assessment
- Water solubility:
- 1 033 g/L
- at the temperature of:
- 100 °C
Additional information
For the evaluation of this endpoint, data from one handbook (CRC handbook) were used as key information. 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". Useful reference books and data compilations containing peer reviewed physico-chemical data include the CRC Handbook of Chemistry and Physics.
Data from this handbook indicate that ammonium thiosulfate has a water solubility of 1033g/L at 100°C. However, no pH value is given.
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.
