What’s being dissolved (lesser amount)
Solute
What’s doing the dissolving (larger amount)
Solvent
Contains the maximum quantity of solute that dissolves at that temperature
Saturated
Contains less than the maximum amount of a solute that can dissolve at a particular temperature
Unsaturated
The amount of solute in a solution
Concentration
Moles solute/liters solution Mol M|L
Molarity (M)
Properties depend only on the concentration of the solute
Ideal solution
Moles solute/kg solvent Mol m|Kg
Molality (m)
G solute/g solution x100
Percent by mass
On adding a solute to a solvent, the properties of the solvent are modified; depend on number of solute particles relative to solvent particles, not the kind of solvent particles
Colligative properties
Colligative properties
Vapor pressure decreases Melting point decreases Boiling point increases Osmosis is possible (osmotic pressure)
