Chapter 10 Objectives 10.1: Define solutions and the different mathematical methods for describing solution composition. 10.2: Provide a qualitative and pictorial description of vapor pressure. 10.3: Discuss Raoult’s Law in a quantitative and qualitative method for describing vapor pressure. 10.4: Outline the role of colligative properties and provide mathematical and qualitative descriptions for colligative properties. 10/2/2009 GT 6e Zumdahl Chapter 10 2
Solution Composition The solute and solvent can be any combination of solid ( s ), liquid ( l ), and gaseous ( g ) phases. Dissolution: Two (or more) substances spread out, or disperse, into each other at the level of individual atoms, molecules, or ions. Solution: A homogeneous mixture 10/2/2009 GT 6e Zumdahl Chapter 10 3 Solvent: Solute: The major component The minor component

Solution Composition Mass percentage (weight percentage): mass percentage of the component = X 100% mass of component total mass of mixture Mole fraction: The chemical amount (in moles) divided by the total amount (in moles) X 1 = n 1 / (n 1 + n 2 ) X 2 = n 2 / (n 1 + n 2 ) = 1 X 1 Define: Mass Fraction , Mole Fraction , Molality and Molarity 10/2/2009 GT 6e Zumdahl Chapter 10 4
Molality m solute = moles solute per kilogram solvent = moles per kg or mol kg -1 10/2/2009 GT 6e Zumdahl Chapter 10 5 Molarity c solute = moles solute per volume solution = moles per liter or mol L -1 Note the difference between Molality and Molarity
