xi is the mole fraction of component i in aqueous solution, T is temperature, and α0 is the measure of the CO2 loading (see Table 3). Expanded uncertainties at 95% confidence are U(T) = 0.02 K, U(α0) = 0.01, U(x2) = U(x3) = U(x4) = 0.0002, and U(μ) = 0.05 mPa s. All measurements were performed at a pressure of 0.1 MPa.
