Description of key information

Water solubility of barium hydroxide: 37.4 g/L at 20 °C (HSDS) and 49.1 g/L at 25°C (CRC handbook). The water solubility of the test substance is dependent on temperature (> 3%/°C according to Gmelin _1932 - supporting study).

Key value for chemical safety assessment

Additional information

Handbook data considered to be from a trusted source acc. to "ECHA, Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance" and therefore, the water solubility stated could be regarded as valid.
