25 °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 compliations containing peer reviewed physico-chemical data include the CRC Handbook of Chemistry and Physics.

Data from this handbook indicate that sodium thiosulfate has a water solubility of 764 g/L at 25°C. However, no pH value is given.
