Water solubility
Administrative data
Link to relevant study record(s)
- 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.
