9/20 - Like dissolves like o No polar compounds dissolve in non-polar solvents o Solvents: SF6 (2 non-metals) soluble in CCl4 o Polar and ionic compounds dissolve in polar solvents o CaCl2 (ionic) soluble in water - Equilibrium in solution formation o Solubility is a measure of the quantity of solute that dissolves in a given quantity of solvent. o Solubility depends on: Solute Solvent Temp Pressure o A saturated solution is a solution where a condition of dynamic equilibrium has been reached between the solid in the solid phase and the solid in the solution o The concentration of a solute in a given solvent at its saturation point is

Unformatted text preview: referred as its solubility. o Supersaturated solution contains more solute that it will contain at the EQ. unstable system-The solubility of gasses o The effect of pressure at a constant temp, the solubility, s of a gas is directly proportional to the pressure of the gas, Pgas, in EQ. With the solution-Colligative Properties o Decrease of vapor pressure o Elevation of boiling point o Depression of melting point o Osmotic pressure-Raoults Law o The vapor pressure of the solvent (pure) decreases because of the pressure of the solute. o Vapor pressure of solution = vapor of the solvent...
