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 (FP) depression: FPsolution > FPpure solvent or
FPsolution < FPpure solvent
b. Boiling point (BP) elevation: BPsolution > BPpure solvent or
BPsolution < BPpure solvent
VIII. Adding Solute to a Solvent (to create solution)
Unsaturated solution –
Saturated solution (called saturation point) – DYNAMIC EQUILIBRIUM
