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

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

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

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.

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

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.

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.
