CHEM 001B Lecture Notes - Lecture 10: Sulfur Dioxide, Carbon Tetrachloride, Intermolecular Force
Document Summary
Extensive dispersion forces limit solubility of molecules in water. Interaction that repels water, diminishes water solubility. Interaction that attracts water, promotes water solubility. The polar molecules nh 3 and hf are soluble in water. The nonpolar molecules ccl 4 and o 2 have only limited solubility in water. At lower temperatures gas dissolved in water has less kinetic energy, and dipole-induced dipole interactions between solute and solvent molecules keep more gas dissolved solute-solvent interactions and reduces solubility. At higher temperatures molecules have more kinetic energy, which overcomes. The solubility of a gas in a liquid such as water depends on the partial pressure of the gas in the air above the surface of the liquid. The quantitative relationship between gas solubility in a liquid and the partial pressure of the gas is known as henry"s law. C gas represents the concentration (solubility) of a gas in a particular.
