Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Not reported

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 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 phys chem. data.

Executive summary:

This information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint At 20ºC and 1013.25 hPa palladium dichloride is red hygroscopic inorganic rhomboid crystals

Description of key information

Palladium dichloride is described as red hygroscopic inorganic rhomboid crystals or a rust coloured powder.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

solid

Additional information

The CRC Handbook (Lide 2008) is a reliable, peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. At 20ºC and 1013.25 hPa palladium dichloride is described as red hygroscopic inorganic rhomboid crystals.

WHO (2002) is a reliable peer reviewed handbook. Palladium (II) chloride is stated to be a rust coloured powder.

The supporting study information (PAMP 2008) is from a Technical Data sheet. The information is considered adequate to use as supporting data. At 20ºC and 1013 hPa palladium dichloride is stated to be an inorganic brown crystal.
