  5. Solution • A homogeneous mixture of two or more substances in a single phase • Particles are thoroughly mixed and remains mixed indefinitely • Components of a solution • Solvent: does the dissolving; the larger amount • Solute: is being dissolved; the smaller amount Chapter 12 Section 1 Types of Mixtures p. 401-406

  6. Liquid and solid solutes p. 402 Chapter 12 Section 1 Types of Mixtures p. 401-406

  7. Solute-Solvent Combinations • Solutes and solvents can be any state of matter. • Look at page 402 for examples • Alloys – solid solutions of metals p. 402 Chapter 12 Section 1 Types of Mixtures p. 401-406

  8. Types of Solutions Image notes Chapter 12 Section 1 Types of Mixtures p. 401-406

  9. Gold and Gold Alloy Image p. 403 Chapter 12 Section 1 Types of Mixtures p. 401-406

  10. Mixtures That Are Not Solutions • Suspensions – particle settle out if not stirred constantly; large particle size • Comparing solutions, colloids and suspensions on page 404 Chapter 12 Section 1 Types of Mixtures p. 401-406 p. 404

  11. Mixtures That Are Not Solutions Colloids • Particle size between suspension & soln. COLLOIDAL DISPERSION DISPERSED PHASEcornstarch DISPERSING MEDIUMwater Chapter 12 Section 1 Types of Mixtures p. 401-406

  12. Tyndall Effect • Occurs when light is scattered by colloidal particles dispersed in a transparent medium Chapter 12 Section 1 Types of Mixtures p. 401-406

  13. Classes of Colloids • Foams and emulsions are types of colloids. • Table on page 404. p. 404 Chapter 12 Section 1 Types of Mixtures p. 401-406

  14. Emulsion Image notes Chapter 12 Section 1 Types of Mixtures p. 401-406

  15. Electrolytes & Nonelectrolytes • Electrolyte – a substance that dissolves in water to give a solution that conducts electric current • Ionic compounds and highly polar molecules form electrolytes • Nonelectrolytes – a substance that dissolves in water to give a solution that does not conduct electricity Chapter 12 Section 1 Types of Mixtures p. 401-406

  16. Electric Conductivity in Solutions p. 406 Chapter 12 Section 1 Types of Mixtures p. 401-406

  17. Ch 12 Sec 1 Homework Section Review Page 406 # 1-6 Chapter 12 Section 1 Types of Mixtures p. 401-406
