Description of key information

Relative density of calcium thiosulphate hexahydrate: 1.87 at approx. 20 °C.

Key value for chemical safety assessment

Relative density at 20C:

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 density of 1.87 g/cm³. According to the reference, the density values can be assumed to refer to temperatures near room temperature. For this reason 20 °C was filled in as temperature.

The relative density was calculated from the value in the handbook. The value was divided by the relative density of water at 4 °C (1.000).
