Product Details

Classic AP Requirement #13—Determination of Enthalpy Change Associated with a Reaction In this experiment, students verify Hess's Law. Three acid-base reactions, chosen so that the third reaction equation equals the first reaction minus the second, are measured for temperature change by calorimetry. The values of heat change and enthalpy of reaction are calculated for each of the three reactions. The reaction results are then compared to verify Hess's Law. Students gain valuable experience with the process of calorimetric determinations. Complete for 24 students working in pairs. Materials Supplied: Hydrochloric acid solution Ammonium chloride solution Sodium hydroxide solution Ammonium hydroxide solution Calorimeters, nested Styrofoam CupsFlinn Transition Guide Available! Adapt this classic AP Chemistry experiment for guided-inquiry and correlate with the AP Chemistry curriculum framework with the Flinn Scientific Inquiry Guidance and AP* Chemistry Curriculum Alignment Guide.
