The experiment began by setting up the LabQuest and preparing a 2M solution of HCl and a 2M solution of NaOH. This was called “Part A”. Two general rules were noted throughout the experiment: add acid to water and pour stock solution into beaker before graduated cylinder. This prevented flash-boiling of the solution, chemical burns, and spills. To make the 2M HCl solution, 200mL deionized water was added to a 600mL beaker labelled “2M HCl” by using a graduated cylinder. Then, 100mL 6M HCl was added to the same beaker also by using a graduated cylinder. The solution was stirred with a stirring rod. To make the 2M NaOH solution, 50mL deionized water was added to a 400mL beaker labelled “2M NaOH”. Then, 100mL 3M NaOH was added to the same beaker.…show more content…
Once 3-4 readings for the solution were collected, the 2M NaOH was added to the solution. The lid was quickly replaced in order to prevent heat from escaping and not being recorded by the temperature probe. The cup was swirled until the temperature reached a peak and began decreasing. After the 180s had passed, data collection ended. The solution was discarded into the waste bin, and the materials were washed. The second reaction in Part B, sodium hydroxide and ammonium chloride, began by saving the data from the first reaction and setting up the LabQuest to new data collection under the same conditions as the first reaction. The cups were restacked and placed in the beaker. Using a graduated cylinder, 50mL 2M NaOH was added to the cup. The cup was then covered and the temperature probe inserted. While the probe was collecting a few initial temperature readings for the solution, 50mL 2M NH4Cl was prepared but not added to the solution. After 3-4 readings were collected, the 2M NH4Cl was added to the solution. The lid was quickly replaced, preventing heat from escaping and not being recorded by the temperature probe. The cup was swirled until the temperature reached a peak and
