Experimental Data

The enthalpy of solution of CO₂ from the temperature coefficient of the Bunsen coefficient is 23.640 kJ mol^-1 (5650 cal mol^-1) in water and 18.577 kJ mol^-1 (4440 cal mol^-1),18.912 kJ mol^-1 (4520 cal mol^-1), and 18.326 kJ mol^-1 (4380 cal mol^-1) for the 0.1, 0.5 and 0.8 mass % Fe₂O₃·xH₂O solution, respectively.
The values for the solubility of CO₂ in water were not given in the paper.
Fe₂O₃·xH₂O is described as a sol (colloidal).
