In a closed system,equilibrium may exist between a gas dissolved in a liquid and the undissolved gas above the liquid. The equilibrium between dissolved and undissolved gas is affected by temperature and pressure. Supplementary Information Increased temperature decreases the solubility of gases in liquids.
Increased pressure increases the solubility of gases in liquids.
Go to top . Fundamental Concepts A solution equilibrium exists when the opposing processes of dissolving and crystallizing of a solute occur at equal rates. A solution exhibiting equilibrium between the dissolved and undissolved solute must be a saturated solution. Go to top . The solubility of a solute is defined as the maximum mass of that solute dissolved in a given volume of solvent under specified conditions.
