【正文】 urated solution: holds more solute than would be in equilibrium with undissolved solute miscibility Miscibility: the mutual solubility of two substances in the same phase. Like dissolves like: Substances that are similar in structure, bonding, and especially in intermolecular forces tend to be highly or even infinitely miscible. Immisicible: Ideal solution Ideal solution of a molecular: the forces between all particle of both solvent and solute are identical. Ideal solution of an ionic solute: the ions in solution are independent of each other and attracted only to solvent molecules. Henry’s law: At constant temperature, the partial pressure of a gas over a solution is directly proportional to the solubility of the gas in that solution standard solution standard solution: a solution of known concentration Concentration of solution: 1. mass (weight) percent= (mass of solute / mass of solution) 100% 2. molarity = moles of solute / liters of solution 3. molality = moles of solute / kilogram of solution colligative property Raoult’s law : The vapor pressure of a liquid in a solution is equal to the mole fraction of that liquid in the solution times the vapor pressure of pure liquid. colligative property: any property of a solution that depends on the relative numbers of solute and solvent particles 5.
