Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP status not known, guideline not known, information from a published handbook, acceptable with restrictions.
Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the Merck Index states that physical data are cited as found in the literature. When several alternate data values appear in the literature, the data is evaluated and representative selections are made; values are then reported with the corresponding source. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of physico-chemical data.
GLP compliance:
not specified
Type of method:
other: Method details not known, but value is taken from a reliable, peer-reviewed handbook
Water solubility:
143 g/L
Temp.:
20 °C
pH:
7
Remarks on result:
other: Temperature and pH not stated, therefore assumed standard
Details on results:
Potassium dicyanoaurate is reported as having a water solubility of 1 gram in 7 mL water, which is equivalent to 143 g/L.
Conclusions:
Interpretation of results: very soluble (> 10000 mg/L)
Potassium dicyanoaurate has a water solubility of 143 g/L.
Executive summary:

Potassium dicyanoaurate has a water solubility of 143 g/L.

No information on the methods used are available. However, this information is taken from a peer-reviewed handbook and so can be considered suitable for use as a key study for this endpoint.

Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of physico-chemical data.

Remarks on result:
other: Temperature and pH not stated, therefore assumed standard
Details on results:
Data not reported
Conclusions:
Interpretation of results: very soluble (> 10000 mg/L)
The water solubility of potassium dicyanoaurate is 14 g/100 mL.
Executive summary:

The water solubility of potassium dicyanoaurate is 14 g/100 mL.

No information on the methods used are available. However, this information is taken from a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint

Description of key information

The solubility of potassium dicyanoaurate in water is 140 - 143 g/L. 

Key value for chemical safety assessment

Water solubility:
143 g/L
at the temperature of:
20 °C

Additional information

The water solubility of potassium dicyanoaurate is taken from two peer-reviewed handbooks (Lide 2008, O'Neil 2006). They are considered suitable for use as key studies for this endpoint.
