c. Tindall Effect –

Most common type of solutions –

II.  Example of Solutions

a. Gas dissolved in liquids
b. Solid dissolved in water

III. Look to last page for space for Salt dissolved in water

Browning motion –

IV. Look to last page for space for Sugar dissolved in water

V. Components of Solutions

a.	Solute –

b.	Solvent –

Most common solvent (called universal solvent)?

VI. Concentrated vs. Dilute

Equation for Molarity (M) = -----------------

VII. Comparing Properties of Pure Solvent to Solution

a.	Freezing point depression FPsolution > FPpure solvent 
 FPsolution < FPpure solvent

b.	Boiling point elevation    BPsolution > BPpure solvent 
 BPsolution < BPpure solvent

VIII.	Adding Solute to a Solvent (to create solution)

Unsaturated solution –

Saturated solution (called saturation point) – DYNAMIC EQUILIBRIUM
