4 Colligative Properties Pogil NAME: AP Chemistry DATE: POGIL: Colligative Properties Part 1 Why? There is a general misconception that adding sodium chloride to cooking water for pasta increases the temperature of the boiling water so that it cooks the pasta faster. NAME: AP Chemistry DATE: POGIL: Colligative Properties Part 1 NAME: AP Chemistry DATE: POGIL: Colligative Properties Part 1 Model 2: Ionic Solutes and Colligative Properties A colligative property is a property that is affected by the concentration of solute particles dissolved in solution. Colligative Properties Pogil - mystiewinckler.com Model 2: Ionic Solutes and Colligative Properties A colligative property is a property that is affected by the concentration of solute particles dissolved in solution. Key Question 6. Explain why the freezing point of m KI (aq) is C, but the freezing point for the m aqueous sucrose solution is C. PRACTICE B. NAME: AP Chemistry POGIL: Colligative Properties Part 2 23 O 6 H O(+ aq ) + Cl (aq) The attraction between solvent water molecules and the solute molecules is initially dipole- dipole, but the attraction between the dissociated ions and the their waters of hydration is ion- dipole. These ion-dipole attractions interfere with recombination to form undissociated molecules. Chem 116 POGIL Worksheet - Week 4 Properties of Solutions The Model: Ionic Solutes and Colligative Properties A colligative property is a property that is affected by the concentration of solute particles dissolved in solution. Key Question 5. Use the Model to explain why the freezing point of m KI(aq) is C instead of C as it is for m C 12 H 22 O 11 (aq). Exercise B. ALE 24. Colligative Properties (Part 2) - Green River College A walkthrough of the responses for the POGIL on colligative properties that we worked together in small groups in class this week. POGIL Colligative Properties Overview and not on the mass or identity of the solute particles. Colligative properties are also affected by temperature. Calculation Colligative Properties Pogil - torticollis.org Non-volatile solutes and Raoult s law. Vapor pressure of solvent in solution containing nonvolatile solute is alwayslower than vapor pressure of pure solvent at same T. At equilibrium rate of vaporization = rate of condensation. Solute particles occupy volume reducing rate of evaporationthe number of solvent molecules at the surface. Colligative Properties - College of DuPage Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. 4 / 5
