Document Summary

Though this does not mean that the relationship is entirely linear because often there is massive variability. Solubility of gasses in water decreases with increasing (hotter) temperatures. Pressure does not really change the solubility of a liquid or a solid. The solubility of a gas in a liquid is proportional to the pressure of the gas over the solution. c-molar concentration of dissolved gas p- pressure (in atm) of gas over solution k- henry"s law constant (mol/l) If there is a mix of gas, then p is pi k constant is specific to gas-solvent combination and vary with temperature. Properties that depend on the number of solute particles in one solution but do not depend on the nature of the solute particles. When a non-volatile solute is dissolved in a liquid, the vapor pressure exerted by the liquid decreases. The difference between the vapor pressure of pure solvent and that of a corresponding solution depends on the concentration.
