Presentation Transcript

  1. Properties of Solutions

  2. CA Standards

  3. Solutions are homogeneous mixtures

  4. Standard 6a Solute A solute is the dissolved substance in a solution. Sugarin soda drinks Saltin salt water Carbon dioxide in soda drinks ·Solid in Solid-Liquid mixtures ·The lesser amounts in liquid-liquid mixtures ·gas in gas-liquid mixtures

  5. Solvent Standard 6a A solvent is the dissolving medium in a solution. Waterin salt water Waterin soda ·Liquid in Solid-Liquid mixtures ·The larger amounts in liquid-liquid mixtures ·Liquid in gas-liquid mixtures Water is the universal solvent!!!

  6. “The Solution Process” Standard 6b What causes solute and solvent to become a solution? Caused by the random molecular motion of the solvent http://www.learnerstv.com/animation/animation.php?ani=122&cat=chemistry

  7. Standard 6c “Factors that Affect the Solution Process” Temperature Agitation (stirring) Surface Area Pressure ( in gas and liquids)

  8. Solubility ·the ability of substance to dissolve ·amount of solute that can dissolve in 100g of water

  9. Solubility Trends Solids tend to dissolve best when: · Heated · Stirred · Ground into small particles Gases tend to dissolve best when: · The solution is cold · Pressure is high

  10. Solubility Chart

  11. “Like Dissolves Like” Nonpolar solutesdissolve best in nonpolar solvents Polar and ionic solutesdissolve best in polar solvents

  12. Homework: Create "Thinking Maps" for the Lecture and use that to write a short summary of the Lecture
