Product Details

College Level Classic General Chemistry Experiment In this experiment, students verify Hess's law. Three acid–base reactions, chosen so 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.
