The Difference between Gas-Liquid Dissolving State and Gas-Liquid Mixing State and Its Verification Tests
Abstract: The aqueous solution of gas solute dissolved in water can be divided into two basic forms: gas-liquid dissolved state and gas-liquid mixed state. The gas-liquid dissolved state is shown as the dissolved state of liquids after the polar reaction or other chemical reactions of gas solute and liquid solvent water. Before and after dissolution, the gas solute is subjected to a process of liquefaction and exotherm. The gas-liquid mixed state is shown as the mixed state of gas and liquid after the gas solute and liquid solvent (water) have no polar reaction or hydration reaction as well as dissociation and association. It is resulted from the uniform diffusion of gas solute into the liquid solvent, that is, the gas solute in the aqueous solution remains a special “gaseous state” in terms of the kinetic energy of gas molecules. As the temperature does not reach the liquefaction point, gas solute does not go through a liquefaction process then. The solubility of gas-liquid dissolved state is generally greater than 1, while the solubility of gas-liquid mixed state is generally less than 1. The gas-liquid dissolved state and gas-liquid mixed state are in line with the applicable conditions of Raoul’s law and Henry’s law respectively, which can be verified by a simple experiment of pentane aqueous solution. Gaseous water is also a form of water existing in the liquid water, the molecules of which can overflow the water surface through evaporation. The experiment shows that the evaporation of water at room temperature is correlated with the water column height or water quantity.
