Reference
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
Qualifier:
no guideline followed
Principles of method if other than guideline:
Not applicable - Handbook data
GLP compliance:
no
Type of method:
other: no data
Specific details on test material used for the study:
No further significant information on test material was stated
Water solubility:
1.25 g/L
Temp.:
20 °C
Remarks on result:
other: no pH given
Details on results:
According to the reference, the water solublity value can be assumed to refer to temperatures near room temperature. For this reason 20°C was filled in as temperature.
Conclusions:
The water solubility of potassium cryolite is 1.25 g/L at 20°C
Executive summary:

According to reliable handbook data (Gmelin Handbook) the water solubility of potassium cryolite is 1.25 g/L at room temperature (assumed 20°C). 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" and therefore, the water solubility of 1.25 g/L could be regarded as valid.
