1. A. Definitions  Solution -  Solution - homogeneous mixture Solvent Solvent - present in greater amount Solute Solute - substance being dissolved

2. A. Definitions Solute Solute - KMnO 4 Solvent Solvent - H 2 O

3. B. Solvation  Solvation –  Solvation – the process of dissolving solute particles are separated and pulled into solution Solid solute is surrounded by solvent particles

4. B. Solvation Strong Electrolyte Non- Electrolyte solute exists as ions only - + salt - + sugar solute exists as molecules only - + acetic acid Weak Electrolyte solute exists as ions and molecules

5. B. Solvation NONPOLAR POLAR “Like Dissolves Like”

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

7. C. Solubility Saturated Solution – contains the maximum amount of solute for a given amount of Solvent.

8. C. Solubility Unsaturated Solution – a solution that contains less solute than the maximum that can be dissolved.

9. C. Solubility Supersaturated Solution – A solution consisting of more solute dissolved than the maximum solubility.

10. C. Solubility SATURATED SOLUTION no more solute dissolves UNSATURATED SOLUTION more solute dissolves SUPERSATURATED SOLUTION becomes unstable, crystals form concentration

11. C. Solubility  Solubility Curve shows the dependence of solubility on temperature

12. C. Solubility  Most solids are more soluble at... high temperatures.  Gases are more soluble at... low temperatures & high pressures (Henry’s Law). EX: nitrogen narcosis, the “bends,” soda
