- 1. Solutions and Suspensions
- 2. What is a Solution? A solution is a mixture in which the constituents are evenly mixed. solute solvent e.g. sugar + water --> sugar solution solute + solvent --> solution
- 3. Different Types of Solution Air Gas Gas Fizzy drinks Gas Alcoholic drinks Liquid Sugar solution Solid Liquid Brass Solid Solid Example of solutions State of solute State of solvent
- 4. Water as a Solvent Water is a common solvent as many substances dissolve in it However, some substances do not dissolve in water e.g. glue and paint.
- 5. What is Solubility? Solubility is the measure of the amount of solute that can dissolve in a solvent.
- 6. Factors that affect solubility The nature of the solute The nature of the solvent Temperature
- 7. What is Rate of Dissolving? The rate of dissolving is a measure of how fast a solute can dissolve completely in a solvent.
- 8. Factors that affect Rate of Dissolving Temperature Rate of stirring Surface area of solute
- 9. Properties of Solutions Solute mix completely and evenly in solvent Light can pass through Filter paper cannot be used to separate solute from solvent
- 10. Common examples and uses Everyday use: Washing clothes Solution Solvent Solute Soap water solution = Water + Soap
- 11. Common examples and uses Everyday use: Sweetening tea and coffee Solution Solvent Solute Sugar syrup = Water + Sugar
- 12. What is a Suspension? A suspension is formed when a solid does not dissolve in a liquid.
- 13. What are Suspensions Suspensions are mixtures of small insoluble particles in a liquid or gas. e.g. Flour water is a suspension.
- 14. How do we create a Suspension? Sandy water suspension Suspension = Water + Sand = Solvent + Insoluble substance
- 15. Properties of Suspensions Suspended particles do not mix completely and evenly Light cannot pass through Filter paper can be used to separate the suspended particles from the suspension
