Details on results:
During this study the water solubility of cobalt chloride hexahydrate was determined using a simplified flask method and was found to be 585783.1 mg/L at room temperature based on a measured cocentration of 145860 mg Co/L.

In this study it was only stated that the test was conducted at room temperature. Because of this it was assumed that the temperature during this study was 20 °C. Also, since no pH was stated in the study, it was assumed that the pH was 7.

Conclusions:
Interpretation of results: very soluble (> 10000 mg/L)
During this study the water solubility of cobalt chloride hexahydrate was determined using a simplified flask method and was found to be 585.8 g/L at room temperature based on a measured concentration of 145.9 g Co/L and 320 g CoCl2/L.

Description of key information

Cobalt chloride hexahydrate has a water solubility of 585.8 g/L.

Key value for chemical safety assessment

Water solubility:
585.8 g/L
at the temperature of:
