1 II. Solubility & Concentration
Ch Solutions II. Solubility & Concentration

2 A. Concentration Concentrated solution large amount of solute
Dilute solution small amount of solute

3 A. Concentration % by Volume liquid in liquid
EX: 10% juice = 10mL juice + 90mL water % by Mass solid in liquid EX: 20% NaCl = 20g NaCl + 80g water

4 A. Concentration UNSATURATED SOLUTION more solute dissolves
no more solute dissolves SUPERSATURATED SOLUTION becomes unstable, crystals form concentration

5 B. Solubility Solubility
maximum grams of solute that will dissolve in 100 g of solvent at a given temperature varies with temperature based on a saturated solution

6 B. Solubility Solubility Curve
shows the dependence of solubility on temperature

7 B. Solubility Solids are more soluble at... high temperatures.
Gases are more soluble at... low temperatures. high pressures (Henry’s Law).
