^ax_i 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(ρ) = 0.0003 g cm^–3. All measurements were performed at a pressure of 0.1 MPa.
