Solutions Review Sheet
1. Solute- substance being dissolved Solvent- Substance doing the dissolving
2. Like dissolves Like – Polar solvents dissolve polar solutes
Nonpolar solvents dissolve nonpolar solutes
3. Table F – Substances that are soluble will dissolve and turn into ions substances
that are not soluble will precipitate.
4. Table G - Any point on line represents a saturated solution
Any point under line represents an unsaturated solution
Any point over line represents a supersaturated solution
Lowest line is least soluble at that temperature
Highest line is most soluble at that temperature
Saturated solutions represent the maximum amount of solute that will dissolve at
a certain temperature in 100gms of water. If given a different
amount of water make a proportion.
5. Table H – Boiling points of different solutions at various vapor pressures.
Boiling point is when vapor pressure equals atmospheric pressure
Normal boiling point when atmospheric pressure is 1atm or 101.3Kpa
6. Colligative properties – Boiling point and Freezing point of a solution are
concentration dependent. The more particles dissolved the higher the boiling
point and lower the freezing point. Remember ionic substances will break into
more than one particle.
7. Concentrations – Percent Mass of part over mass of whole X 100
Molarity is number of moles per liter of solution. M=m/L
Moles equal molarity X liters
Parts per million equals mass of solute divided by mass of solution times 1
million.
