Physical Science - Chapter 9

Solutions

9A: Mixtures and Solutions

  • Types of Heterogenous Mixtures

    • Suspension: a heterogenous mixture of a fluid and large particles that will settle out over time

    • Colloid: a heterogenous mixture in which the dispersed particles will not settle out

  • Solvation: the process of dissolving a solute into a liquid

    • Dissociation: the physical separation of the ions in a solid ionic compound by the action of a solvent

  • solubility: The maximum amount of solute into a liquid solvent

  • Separating Mixtures

    • Evaporation

    • Magnetism

    • Filtering/Sifting

    • Distillation

9B: Solution Concentration

  • Saturation

    • Concentration: the actual amount of solute dissolved in a given amount of solution

    • Saturated Solution: a solution that contains the maximum amount of solute that it can hold at a given temperature

    • Unsaturated Solution: a solution that contains less than the maximum amount of solute that it could hold at a given temperature

    • Supersaturated Solution: a solution that contains more than the maximum amount of solute that it can normally hold at a given temperature

Colligative Properties

  • Colligative Property: a physical property of solutions that depends only on the concentration of dissolved particles and not on the identity or properties of the solute

    • Boiling Point Elevation: the increase in the boiling point of a solvent due to the presence of dissolved solute

    • Freezing Point Depression: the lowering of the freezing point of a solvent due to the presence of a dissolved solute
