Details on results:
During the study the water solubility of cobalt propionate at 20 °C and at 37 °C were determined using the flask method and was found to be 74860.1 mg/L at 20 °C (after 72 hours of shaking) based on a measured concentration of 21185.4 mg Co/L and 75684.6 mg/L at 37 °C (after 72 hours of shaking) based on a measured concentration of 21418.8 mg Co/L.
Conclusions:
Interpretation of results (migrated information): very soluble (> 10000 mg/L)
