Document Summary

Result of interacting imf of solute and solvent. Amount of the substance that dissolves in a certain amount of solvent. Measure of energy randomization/ dispersal within a system. Solutions form in order to achieve greater entropy and spread out. Formation of a solution: driven by the tendency of mixing or towards greater entropy. Effect of imf: solvent- solute interaction, solutions form when, solvent-solute solute-solute or solvent-solvent, small disparity (like dissolves like) Similar imf: solvent- solvent interaction, solute- solute interaction. Solution w/ less than the equillibrium amount of solute. Solution w/ more than the equillibrium amount of solute. Solubility of solids in water increases w/ temp. Solubility of gases in water decrease w/ temp. Solubility of a gas increases as pressure increases. Amount of solute in a given amount of solution. Good for comparing concentrations over a range of diff temps. Ratio of the mass of the solute to the mass of solution.
