Type of information:

Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
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.

Density:
3.9 g/cm³
Remarks on result:
other: In solid form
Conclusions:
When solid, the density of tetrachloroauric acid is 3.9 g/cm3.
Executive summary:

No information on the methods used is 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. When solid, the density of tetrachloroauric acid is 3.9 g/cm3.

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.

Description of key information

When solid, the relative density of tetrachloroauric acid is 3.9.

Key value for chemical safety assessment

Relative density at 20C:
3.9

Additional information

Information on density is available from two peer reviewed handbooks (O’Neil 2006, Lide 2008). Although the methods used are not known the handbooks are considered reliable and suitable for use as key studies for this endpoint. When solid, the relative density of tetrachloroauric acid is 3.9.
