Solubility of CO2 in aqueous solutions of NaCl, KCl, CaCl2 and their mixed salts at different temperatures and pressures

▶ NaCl, KCl, CaCl2 and their mixtures affect the solubility of CO2 in water significantly. ▶ The solubility of CO2 in the low pressure range is more sensitive to pressure. ▶ The salting-out effect of a salt mixture is between those of its components.
