PROBLEM TO BE SOLVED: To provide a water soluble gel in which a gas is dissolved and retained to remarkably increase the solubility of the gas such as gaseous oxygen, ozone gas and carbon dioxide gas or the like to water under ordinary temperature and atmospheric pressure without contaminating ...
Why Carbon Dioxide is Soluble in Water? The solubility of carbon dioxide in water is higher than other gases for a few reasons. Carbon dioxide, while the molecule is not considered polar due to its symmetry, has polar bonds between carbon and oxygen. Oxygen is more electronegative th...
