Measuring The Heat of Decomposition of Hydrogen Peroxide Lab Report

beat The Heat of Decomposition of Hydrogen Peroxide - Lab Report ExampleThe objectives are threefold to beatnik the temperature change of a H2O2 solution as it decomposes, to measure the amount of heat absorbed by the calorimeter and finally to calculate the calorimeter constant and then(prenominal) use it to determine the enthalpy of decomposition.The Lab Quest social unit was turned on and the temperature try plugged in. A 150-mL beaker was wrapped in towel paper and then pose inside a 250-mL beaker. A piece of aluminium foil big enough to intersect the top of the two beakers was cut.25 mL of crisp water was measured using a calibrated cylinder and poured onto the 150-mL beaker.. 25 mL of hot water was measured into the graduated cylinder and the temperature measured. The temperature probe was placed into the cold water solution in the 150-mL beaker. The Lab Quest unit was then set up to begin recording the temperature by pressing the green button. 25 mL of the hot water was poured into the 150-mL beaker containing the cold water. The cup was then quickly covered with the aluminium foil. The cups were periodically swirled to ensure the contents mixed.Temperature recording was stop once the temperature began to decline for several minutes. The used water was then poured into the sink. The recorded temperature and time data were entered into an outgo spreadsheet. The steps above were repeated twice and the average value calculated.250 mL of H2O2 was obtained. The temperature of the H2O2 was measured and recorded as the initial temperature of the solution and calorimeter. The concentration of the H2O2 was also recorded. 60 mL of 0.5M KI solution was obtained. 40 mL of the H2O2 solution was measured into a graduated cylinder and the temperature probe plugged in. 10 mL of KI was measured into another graduated cylinder and then poured into the calorimeter and then quickly covered with an aluminium foil lid. The temperature probe was immediately inserte d into the probe through a sight in the foil lid. The temperature recording
