A calorimeter was made by using a beaker was placed in a Styrofoam cup on top of a magnetic stirrer that was set to 1000rpm. A magnetic stirrer bar was placed inside the beaker. To calibrate the calorimeter, a neutralisation reaction was done. 25ml of 2M hydrochloric acid (HCl) solution was added into the beaker. A temperature probe, connected to LabQuest, was pierced through the lid of the Styrofoam cup before covering the beaker. LabQuest was set at a rate of 12 samples/min with a duration of 10 minutes. Recording of temperature data, by LabQuest, was initiated when the solution temperature has settled. 25ml of 2.05M sodium hydroxide (NaOH) solution was then added into the beaker. After the data has been collected, a second trial was conducted.
After calibration, hydrogen chloride was replaced with 40ml of 6% hydrogen peroxide (H2O2) solution in the beaker that was placed in the Styrofoam cup. The lid with the temperature probe was then placed back on the Styrofoam cup. Recording of temperature data by LabQuest was initiated when the temperature had settled. 10ml of 0.5M ferric chloride (FeCl3) solution was then added into the beaker. After data has been collected, a second trial was conducted.
