Document Summary

12. 2 types of solutions and solubility: aqueous solution: water is the solvent and solid, liquid or gas is the solute, solubility of a substance is the amount of substance that will dissolve in a given amount of solvent. Two gases mix b/c of entropy but not because of lowering potential energy (remains unchanged: entropy: a measure of energy randomization or energy dispersal in a system. Neon and argon gas both has kinetic energy confined in a system with any temp. above 0k, when gases mix, ek spreads out/dispersed over a larger volume therefore mixture of gases has greater energy dispersal/greater entropy. Intermolecular forces exists between: solvent-solute, solvent, and solute particles. H2o has strong h-bonding attraction but cannot form hydrogen bond w/ hexane. energy to pull h2o molecules is too great and too little energy is retuned when the water molecule interacts with hexane therefore solution is not formed.
