7. After 4 minutes, quickly remove the lids from both calorimeter, pour the cold water from calorimeter B to calorimeter A, replace the lid, and continue taking the temperature readings for the next three minutes. Part B: Enthalpy of Neutralization of Aqueous HCl and NaOH 8. Measure 50.0mL of 1.0M HCl into calorimeter A and 50.0 1.0M of NaOH into calorimeter B. 9. Read the temperatures of each solution at 1-minute intervals for 3 minutes. 10. At the three minute mark, quickly pour the NaOH into calorimeter A and stir thoroughly 11. Continue reading the temperature for another 5 minutes at 1 minute intervals 12. Pour the solution in the calorimeter into a large beaker to combine with the other part and neutralize. Part C: Enthalpy of Solution of Solid NaOH 13. Measure 50.0 mL of 1.0M HCl into calorimeter A. 14. Weigh accurately (to ± 0.001 g) about 2.0g of NaOH pellets into a small bother with a cap. First make sure to measure the mass of the bottle with the cap and then subtract the mass of the bottle with cap and the NaOH pellets. 15. Read the temperature of the water at 1-minute intervals for 3 minutes.
16. At the three minute mark, quickly pour the NaOH into calorimeter A and stir thoroughly 17. Continue reading the temperature for another 5 minutes at 1 minute intervals 18.
