CHM 2046 Chapter Notes - Chapter 12: Supersaturation, Enthalpy, Dynamic Equilibrium
Document Summary
Water is the solvent and a solid, liquid or gas is the solute. Nature"s tenancy toward mixing = spontaneous mixing. Liquid solution: gas and liquid, liquid and liquid or liquid and solid. Ex. club soda (co2 and water), vodka (ethanol and water), seawater (nacl and water) Amount of substance that will dissolve in a given amount of solvent. Dependent on intermolecular forces and tendency toward mixing. Mixing does not mean lowering potential energy. Entropy: measure of energy randomization or energy dispersal in a system. When two gases are mixed, they have greater entropy than when separated. Either promote formation of mixture or prevent it. A solution always forms if solvent-solute interactions are = or > solvent-solvent interactions and solute-solute interactions. Miscible: soluble in each other in all proportions. If solvent-solute interactions are weaker than solvent-solvent and solute-solute interactions, then a solution may or may not form dependent on disparity.
