Mixtures & Solutions PPT

  1. 1. Mixtures and SolutionsMixtures and Solutions Can You See The Phases?
  2. 2. A mixture is made of 2 or more types of atoms that are NOT chemically combined together. Mixtures can take many forms: 2+ Solids 2+ Gases What Is A Mixture?What Is A Mixture? 2+ Liquids ANY combination of solids, liquids & gases
  3. 3. Mixtures of SolidsMixtures of Solids
  4. 4. Mixtures of LiquidsMixtures of Liquids
  5. 5. Mixtures of GasesMixtures of Gases
  6. 6. Types Of MixturesTypes Of Mixtures There are 2 major types of mixtures: Heterogeneous Homogeneous You can see the different parts (phases) of the mixture easily Means “different” Means “the same” You cannot see the different parts (phases) of the mixture
  7. 7. Heterogeneous MixturesHeterogeneous Mixtures
  8. 8. Homogeneous MixturesHomogeneous Mixtures
  9. 9. Which Kind of Mixture?Which Kind of Mixture? Classify each type of mixture as: Heterogeneous Homogeneous Heterogeneous HeterogeneousHomogeneous
  10. 10. A solution is a special type of mixture. SolutionsSolutions A solution is a homogeneous mixture that combines a solute and a solvent. A solution involves one substance dissolving in another substance, which is usually a liquid.
  11. 11. A solution is a special type of mixture. SolutionsSolutions A solution is a homogeneous mixture that combines a solute and a solvent. The solid part that gets dissolved. e.g. salt, sugar The liquid part that does the dissolving. e.g. water Solute Solvent
  12. 12. A solution is a special type of mixture. SolutionsSolutions A solution is a homogeneous mixture that combines a solute and a solvent. The solid part that gets dissolved. e.g. salt, sugar The liquid part that does the dissolving. e.g. water Solute Solvent
  13. 13. How To Make A SolutionHow To Make A Solution Solute Solvent Solution+ = Salt Water Salt Solution
  14. 14. We can measure how easily a solute will dissolve in a certain solvent. SolubilitySolubility This measurement is called solubility. The solute dissolves quickly & easily e.g. salt in water The solute does not dissolve easily e.g. sand in water HIGH Solubility LOW Solubility
  15. 15. We can add a LITTLE or a LOT of solute! Dilute vs. ConcentratedDilute vs. Concentrated For example, putting spoonfuls of sugar into a cup of tea… A solution with only a small amount of solute is called a dilute solution.
  16. 16. We can add a LITTLE or a LOT of solute! Dilute vs. ConcentratedDilute vs. Concentrated For example, putting spoonfuls of sugar into a cup of tea… A solution with a large amount of solute is called concentrated.
  17. 17. Eventually, a solvent can’t hold anymore! Saturated SolutionsSaturated Solutions A saturated solution CANNOT hold any more solute at a certain temperature.
  18. 18. But, by heating a solvent up, we can make it hold even more solute than normal. A super-saturated solution contains more solute than it can normally dissolve. Keep Going!Keep Going! Heat It!
