Lecture #4 Solubility of solid solutes in liquid solvents with Temp. (normally) Solubility (g solute in 100 g H 2 O) Temp. ( o C) unsaturated supersaturated Line is limit of solubility (in a saturated solution, some solid is present) X cooling Random unsaturated solution Some solute will precipitate on cooling random unsaturated solution In an extreme case where solvent freezes: (1) all solute precipitates (2) pure solvent forms as a solid Cooling causes separation of mixture UNFAVORABLE Due to natural tendency for soluble substances to mi UNFAVORABLE Due to natural tendency for soluble substances to mix Pressure Temp. ( o C) Pure Mp/Fp line Solution Mp/Fp line Pure Vp/Bp line Solution Vp/Bp line Solid Gas Liquid Δ T f Δ T B P soln Freezing point depression Boiling point Elevation Vapor pressure Lowering Directly related because definition of Bp is when Vp = atmospheric pressure
