1. Solubility CN What is solubility?
The measure of how much of a substance can dissolve in another substance at a given temperature.

2. Solubility CN What is solubility?
Solute – the substance that is dissolved.
Example – sugar, salt
Solvent – the substance that does the dissolving.
Example – water, cooking oil
Solution – the mixture that is formed when a solvent dissolves a solute.
Example – salt water

3. Solubility CN What are the different types of solutions?
Diluted – a solution with little solute dissolved
Concentrated – a solution with a large amount of solute dissolved

4. Solubility CN What are the different types of solutions?
Unsaturated – a solution that can still dissolve more solute.
Saturated – a solution that cannot dissolve more solute.
Supersaturated – a solution that dissolves more solute than expected due to an increase in temperature.

5. Solubility CN How do you calculate the concentration of a solution?
Mass of solute x 100
Mass of solution
Example – 16 g of salt dissolved in 150 mL of water.
1 mL of water has a mass of 1 g.
16 x 100 = 10.7 %
166

6. Solubility CN What affects solubility?
Pressure – the higher the pressure the more gas will dissolve.
Temperature – the higher the temperature the more solids will dissolve but the less gas will dissolve.

7. Solubility CN What affects solubility?
Polarity – the arrangement of particles in a substance
Polar solvents only dissolve polar solutes
“Like dissolves like”
Water is polar and only dissolves polar solutes.
