Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
No method stated, result from published paper.
GLP compliance:
not specified
Type of method:
other: Original publication not available. Information taken from Gmelin - Handbook of Inorganic and Organometallic Chemistry
Specific details on test material used for the study:
Measurement performed on zinc hexafluorosilicate hexahydrate
Key result
Water solubility:
715 g/L
Conc. based on:
test mat.
Temp.:
20 °C
pH:
< 3.2
Details on results:
The substance is not stable at pH>3.2. If dissolved in demineralized water the substance decomposes resulting in the formation of hydrogen fluoride and zinc ions. The pH value will decrease until stable cpH-conditions for the substance are achieved.
Conclusions:
The solubility in water was determined as 715 g/L at 20 °C and a pH value <3.2.
