Assignment for Tuesday (November 6th) through Thursday (November 8th)
Chapter 13. Properties of Solutions
Read and study the following pages: pg 528-562
Be able to answer in class
on Tuesday Visual problems 1-10 on pp 564-565
Assigned problems
at end of chapter: pp 566-572.
Problems: 14, 19, 22, 30,
31, 35, 39, 42, 50, 57, 60, 70, 74, 76, 82, 85
Optional:
2 Pt bonus problems to hand
in at start of Tuesday Lecture: Problems: 92, 97,104 and 108
Items to focus on:
[solute. solvent and
solution], solution process (energy considerations), solubility, temperature and
pressure effects on solubility (Henry's Law), concentration and converting
concentrations (mass % (m/m), volume % (v/v) mas/volume % (m/v). Molarity (M)
and molality (m). colligative properties (Raoult’s Law, boiling point elevation
and freezing point depression, osmosis & osmotic pressure), colloids, van’t Hoff
factor (pg 557)
Note:
Colligative properties depend on the
quantity (concentration) but not the type or identity of the solute
particles. For colligative properties, the molality (moles of solute/Kg of
solvent) depends on whether the solute is a nonelectrolyte (no dissociation)
or an electrolyte (complete dissociation). For example, a 2 m solution of
sugar in water is 2 m whereas a 2 m solution of calcium chloride (CaCl2)
is 3 m for purposes of ‘colligative properties calculations’.

how the equation can be used to find the normal BP of a liquid given the vapor
pressure of the liquid at a specific temperature and the heat of vaporization (∆H
vaporization).
