The solubility of CO2 in water, expressed as mole fraction of CO2 in the liquid phase, is given for pressures up to atmospheric and temperatures of 0 to 100 °C. Note that 1 standard atmosphere equals 101.325 kPa. The references give data over a wider range of temperature and pressure. The estimated uncertainty is about 2%.
15 cze 2003 · The solubility of CO 2 in water is modelled according to the following reaction equilibrium: (1) CO 2(vap, liq) = CO 2(aq), where CO 2(vap,liq) stands for carbon dioxide in the CO 2-rich vapour or liquid phase, and CO 2(aq) denotes all aqueous species of CO 2 lumped together.
Like water, carbon dioxide is one of the most studied substances in the annals of science. It has a readily accessible critical point (30.98°C and 73.77 bar), and it is relatively safe (compared with
18 lut 2015 · For this conversion the density of carbon dioxide was calculated using the truncated virial equation. Second virial coefficients were taken from Angus et al. (10). The density of water was taken from The Steam Tables (11).
1 lis 1974 · Solubility coefficients for carbon dioxide in water and seawater are calculated for the data of Murray and Riley, and are fitted to equations in temperature and salinity of the form used previously to fit the solu- bilities of other gases.
18 lut 2015 · Comparison of the smoothed mole fraction solubilities of CO 2 in D 2 O (from Table 1) with corresponding solubilities of CO 2 in H 2 O (Carroll & Mather, CO 2 - H 2 O section, “The Solubility of Carbon Dioxide in Water at Low Pressure”, Table 1, Eq.
Although carbon dioxide has polar carbon-oxygen bonds, the linear structure predicted by the Lewis structure and VSEPR theory and verified experimentally leads to the prediction that carbon dioxide should be non-polar and have low solubility in very polar water.
