- 1solutionHomogenous mixture composed of solute and solvent
- 2"like dissolves like"*a polar solute will dissolved in a polar solvent.
*a non polar solute will dissolved in a non polar solvent. - 3Unsaturated SolutionSolution that in which addition of solute will not result a precipitant
- 4Saturated SolutionSolution that in which any addition of solute will result a precipitant
- 5Dilute Solutionsolute mole fraction = 0
ex. a bath filled with water containing 1 spoon of salt - 6Supersaturated SolutionSolution made by forced conditions as high pressure
- 7Hydration energythe attractive forces of water exerted on the ions of solute.act with solution process
- 8Lattice energyEnergy of ionic bonds which act against the solution process
- 9Solubilityis the ability of s solute to be dissolved in a solvent (water) during the solution process
- 10Factors affecting solubility1.Concentration
2.temp
3.pressure - 11Dalton lawP(total)=p(1)+p(2)+...
states that total pressure is the sum of all partial pressures exerted at that volume - 12Ideal Gas LawPV=nRT
- 13colligative propertiesare properties of solution that depend only on the solute concentration and not size ,weight or chemical behavior
- 14Colligative properties are:1.vapor pressure
2.Tb-boiling point and Tf freezing point
3.Osmotic pressure - 15Vapor pressureis the pressure of the vapors over solution/water
- 16Boiling pointThe temp in which the Vp is equal to atm pressure
- 17freezing pointthe point in which solvent molecules form the max amount of intermolecular bonds ,change their state of matter from liquid to solid
- 18osmosisflow of water through semi permeable membrane from a low concetration to high salt concentration (hypotonic to hypertonic)
- 19osmotic pressurethe pressure exerted by the water on semi-permeable membrane during osmosis process
- 20osmotic pressure calculation
