    1. II. Factors Affecting Solvation (p. 471 – 477) Ch. 16 –Solutions

    2. A. Solvation Solvation – the process of dissolving

    3. A. Solvation

    4. B. Solvation Dissociation separation of an ionic solid into aqueous ions

    5. B. Solvation Ionization breaking apart of some polar molecules into aqueous ions

    6. B. Solvation Molecular Solvation molecules stay intact

    7. B. Solvation Soap/Detergent polar “head” with long nonpolar “tail” dissolves nonpolar grease in polar water

    8. B. Factors Affecting Solvation Molecules are constantly in motion according to… Kinetic Theory When particles collide, energy is transferred

    9. B. Factors Affecting Solvation Solubility = amount of a substance that will dissolve in a liquid Smaller pieces of a substance dissolve faster b/c of larger surface area Stirring or shaking speeds dissolving b/c particles are moving faster and colliding more Heating speeds dissolving (see above) Not all substances dissolve

    10. C. Solubility Water is universal solvent b/c of its polarity If something can dissolve in something else, it is said to be soluble If it cannot dissolve, it is said to be insoluble “Like dissolves like”

    11. C. Solubility

    12. C. Solubility

    13. C. Solubility Solubility Curves maximum grams of solute that will dissolve in 100 g of solvent at a given temperature varies with temp based on a saturated soln

    14. C. Solubility Solubility Curve shows the dependence of solubility on temperature

    15. C. Solubility Solids are more soluble at... high temperatures.
