a) *w*_{2} = mass fraction of CaCl_{2}

b) Based on moles of H_{2}O, CaCl_{2} and CO_{2}

c) Solid CaCO_{3} was also present during this set of measurements.

Salt solution and gas were charged to a 300-ml copper-lined vessel supported in a heater, and were equilibrated by rocking. Temperature was measured by a copper constant thermocouple placed in a well in the vessel; pressure was measured by a Crosby deadweight balance. Samples were withdrawn from the bottom of the vessel into a glass trap; the gas evolved from the sample was measured in a water-jacketed buret over mercury at atmospheric pressure, and the solution residue was weighed. Correction was made for the volume of gas still dissolved in the solution. The total volume was reduced to STP and the number of moles was obtained from the molar volume of carbon dioxide, taken as 22,264 cm^{3}. Measurements on a charge of solution were made first at the maximum pressure, after which the pressure was reduced by venting gas. Equilibration and sampling was repeated for measurements at lower pressures.
