16 wrz 2022 · A common example is the dissolving of carbon dioxide in water, resulting in carbonated water. Carbon dioxide is weakly soluble in water, therefore it separates into a gas when the pressure is released. This process is generally represented by the following reaction, where a pressurized dilute solution of carbonic acid in water releases gaseous ...

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.
The table below gives thermodynamic data of liquid CO 2 in equilibrium with its vapor at various temperatures. Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0 °C temperature and 3483 kPa pressure.
Specific Properties. The tabulated values for the enthalpy, entropy, and heat capacity are on a molar basis. In order to convert them to the specific property (per unit mass), divide by the molar mass of carbon dioxide (44.010 g/mol). H = h / M.
Although CO 2 has no dipole moment it is very polar (dielectric constant = 1.60 at 0 °C, 50 atm) and consequently dissolves in polar solvents such as water up to a concentration of 18% (0.04 M).
18 lut 2015 · The solubilities calculated using the model of Carroll et al. (2) were then converted to Ostwald coefficients (volume of gas per unit volume of solvent, both at the specified temperature). For this conversion the density of carbon dioxide was calculated using the truncated virial equation.
