Additional information

Gregory (2014) is a published article in peer-reviewed literature. Water solubility was measured following OECD TG 105, and the results are considered to be suitable for use as the key study for this endpoint. The water solubility of dipotassium hexachloroplatinate was determined to be 11.0 g/L.

Lide (2008) is a peer-reviewed handbook and results from this handbook are considered to be suitable for use as supporting data.

The solubility of potassium hexachloroplatinate is 0.77g/100g H2O at 20°C.
