Solutions Homogeneous Mixture of 2 or more Substances

Some Terminology Solvent – The substance that “does the dissolving” Solute – The substance that “gets dissolved” Solution – The resulting mixture

Why Do Solutions Form?

Why Isn’t Everything Soluble in Everything?

Some Concentration Units Molarity - # mol solute / # L solution Molality - # mol solute / # kg solvent Mole Fraction of substance - # mol / total mol Mass Percent of Solute 100% (solute mass / solution mass)

Time to do some calculations! Calculation of concentration units Conversion of one concentration unit to another

Colligative Properties Vapor Pressure Lowering – Boiling Point Elevation – Freezing Point Depression Osmotic Pressure

Why Does a Solute Lower Vapor Pressure?

Solute Reduces Rate of Evaporation

Equilibrium Reestablished at Lower Pressure

Raoult’s Law

Why Does Vapor Pressure Lowering Change the Boiling and Freezing Points?

Raoult’s Law Applied to Two Volatile Components in a Solution
