Description of key information

Water solubility of calcium thiosulfate hexahydrate: very soluble 

Key value for chemical safety assessment

Water solubility:
1 000 g/L
at the temperature of:
3 °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 calcium thiosulfate hexahydrate has a water solubility of 1000 g/L at 3°C. However, no pH value is given.
