2. Based on your graph, is the dissolution of NaOH (s) an endothermic or exothermic process? The surroundings here are the entire solution and the calorimeter. The system is the solid NaOH that is dissolving. Therefore, since we know that heat flows between the system (qdiss) and the surroundings (qon +9cal), we can rearrange Eqn. 8.7 to become: -Adiss 9soln +9cal 3. What is the initial temperature of solution & calorimeter? 4. What is the final temperature of the solution & calorimeter? 5. What is the mass of water (s) used? 6. What is the mass of NaOH (s) used? 92 50mL = 0,05 litby 0,05litter x 40 29. 21.3 31 50 2 (8.13) °C °C g

Summer 2022 Experiment 8 7. What is the total mass of the solution? 8. In order to calculate the heat content of the solution, we must first figure out the specific heat capacity of the solution. The heat capacity of water is 4.184 J/g C, of 1.0 M NaOH is J/g Cand of 0.5 M NaCl is 4.00 J/gºC. What is the correct specific heat capacity to use for the solution? 9. Calculate the heat content of the solution (q) Show your work! 10. Calculate the total heat content of the calorimeter (q). Show your work! 11. Calculate the heat of dissolution of qs of NaOH(s) Show your work! Also, check that this sign fits your expectations. CHEM 1215 52 93
