A dissolved gas is, simply enough, gas that has been dissolved into another material. This creates a solution, a mixture, where the gas is the solute, the minor component, and the other material, generally a liquid, is the solvent, the main component.
Definition of Solubility of Gases. The amount of a gas which will dissolve in a liquid chiefly depends upon the gas pressureâthe greater the gas pressure, the greater its solubility. Gas solubility will be even greater if the gas reacts with the solvent, e.g., ammonia and carbon dioxide in water. Gas solubility is quantitatively described by Henryâs law, which states that the amount of a gas dissolved in a liquid at a fixed temperature depends only upon the gas pressure. This is true for both pure gases and mixtures of gases.
