Transcript

  • 1. MOLARITY
  • 2. MOLARITY A unit on concentration that is the ratio between moles of DISSOLVED substance and liters of solution
  • 3. Molarity (M) = moles of solute (mol) volume of solution (L)
  • 4. There are many ways to represent molarity:
    • Molarity
    • M
    • Molar
    • mol / L
  • 5. MAKE SURE YOUR UNITS ARE CORRECT!!! ALWAYS mol/L
  • 6. Homogeneous Mixtures are also known as SOLUTIONS! !
  • 7. Solutions are made up of two parts
    • Solute
    • Solvent
  • 8. SOLUTE the part of a solution present in the LEAST amount (what is dissolved)
  • 9. SOLVENT the part of a solution present in the greatest amount (what does the dissolving)
  • 10. SOLUTION!!! = Solvent Solute
  • 11. Solubility amount of solute that will dissolve in an amount of solvent at a given temperature
  • 12. Saturated Solution contains the maximum amount of solute for an amount of solvent at a given temperature
  • 13. Unsaturated Solution contains less solute than a saturated solution
  • 14. Supersaturated Solution contains more solute than it should theoretically be able to hold at a certain temp
  • 15. MOLARITY A measurement of concentration of a solution
  • 16. MOLARITY moles of solute divided by liters of solution
  • 17. MOLARITY
  • 18. Colligative Property property of a solution that depends only on the concentration of the solution
  • 19. Two Main Colligative Properties:
    • Boiling Point Elevation
    • (Ex: Antifreeze in cars)
    • Freezing Point Depression
    • (Ex: Salt on icy roads)
