During part A of the experiment, the solution and LabQuest was prepared. The 300 ML solution of HCL solution was prepared through the addition of 200 ML of deionized water and
100 ML of 6 M HCL. This solution was labeled “2 M HCL”. The solution was stirred with a glass stirring rod. Next, a 150 ML of 3 M NaOH was prepared through the addition of 50 ML of deionized water and 100 ML OF 3 m NaOH solution. This was labelled “2 M NaOH”. The solution was stirred with a glass stirring rod. It was important to remember that diluting the solutions would produce heat and to use the solutions in reactions 1-5, it was important that the solutions cooled down to room temperature. For the next part of the experiment, the LabQuest needed to be set up. The LabQuest was plugged in and turned on, then the temperature probe was attached to channel one. The graph was then set up through clicking “Sensor View” and changing the “Time Based” data and interval. The interval was changed to 15 seconds and the derived settings were saved. During part B of the experiment, the reaction of Hydrochloric Acid and Ammonium hydroxide were conducted. During reaction 1, Hydrochloric acid was combined with
Ammonium Hydroxide. To do this, two Styrofoam cups were stacked together and placed into a beaker. 50 ml of the “2 M HCL” solution prepared in step 1 was added to the Styrofoam cup.
The Styrofoam cup was then covered with a plastic lid and the temperature probe was inserted into the solution, making sure
