Unformatted text preview: 1. Energy is absorbed to open pockets in the solvent that can hold gas molecules 2. Energy is released when gas molecules are popped into these pockets. 3. Heats of soln for gases in organic solvents are often endothermic 4. heats of soln for gases in water are often exothermic (pockets already open) saturated solution dynamic equilibrium exists between the un-dissolved solute and the solute in the solution A SUBSTANCES SOLUBILITY CHANGES WITH TEMPERATURE (gas and liquid) GASES BECOME MORE SOLUBLE AT HIGHER PRESSURES HENRYS LAW pressure solubility law C gas = k H P gas GASES WITH POLAR BONDS IN THEIR MOLECULES ARE MORE SOLUBLE IN WATER...
