temperature readings for the next three minutes. Now, draw a graph and do the calculations. Part B: The heat of neutralization of aqueous HCl and NaOH 7. Measure 50 mL of 1.0 M HCl into calorimeter A and 50 mL of 1.0 M NaOH into calorimeter B. Cover each with a lid and record the temperature for each at 1 minute intervals for 3 minutes. 8. Quickly pour the NaOH solution in calorimeter A. With the lid on, stir the solution and record the temperature for another 5 minutes at 1 minute intervals. Now, draw a graph and do the calculations. Part C: The heat of solution of solid NaOH 9. Measure 50 mL of distilled water into calorimeter A. 10. Weigh out 1.8 – 2.0 grams of NaOH. 11. Measure the temperature of the water in the calorimeter at 1 minute intervals. After 3 minutes, add the NaOH to the water and place a lid on it. Then stir the solution while recording the temperature at 1 minute intervals. Allow the NaOH to dissolve and continue monitoring the temperature for at least 4 minutes. Then draw the graph and do the calculations.Part D: The heat of neutralization of solid NaOH12. Repeat the same produce for part C except instead of dissolving solid NaOH in distilled water, use 50 mL of 1 M HCl in calorimeter A instead.13. Calculate the molar enthalpy associated with this reaction.
