This preview shows page 4 - 5 out of 12 pages.

Part 2: Hydrochloric Acid and Magnesium 1. Using a 100 mL graduated cylinder obtain about 75 mL of hydrochloric acid solution and measure the volume to the nearest 0.1 mL. Record the volume in the Data Sheet. Pour this solution into the calorimeter and place the temperature probe into the solution. 2. Start the Logger Pro application. Open the folder Chemistry with Computers. Then open the file Endo-Exothermic. Using the Experimentmenu select Data Collection. Set the experiment length to 500 seconds. Set the sample rate to 0.5 samples/second. Oversampling should not be selected. 3. Double-click on the graph to select Graph Options. Set the time scale (x-axis) to 0 sec to 500 sec. the temperature scale (y-axis) to 0°C to 60°C. Enter a title for the graph. 4. Obtain a 12 cm long sample of magnesium metal. Record the mass to the nearest 0.1 mg in the data sheet. Fold the magnesium metal into a ribbon so that it is fully submerged when it is dropped into the hydrochloric acid solution. 5. Begin collecting data. The data should appear as a curve in the graph window. After you have at least thirty seconds of data displayed on the graph quickly add the magnesium ribbon to the hydrochloric acid solution in the calorimeter. Quickly place the temperature probe back into the solution. 6. The cork should not be pushed in tightly over the calorimeter opening. Begin gently swirling the calorimeter for the length of the experiment. 7. The instrument should stop taking data automatically after 500 seconds. Waste can be disposed of in the sink. Rinse and dry the calorimeter using deionized water. 8. Determine the change in temperature of the reaction as described on page 6 before moving to the Part 3. 9. Print the graph in landscape format. Part 3: Hydrochloric Acid andMagnesium Oxide 1. Using a 100 mL graduated cylinder obtain about 100 mL of hydrochloric acid solution and measure the volume to the nearest 0.1 mL. Record the volume in the Data Sheet. Pour this solution into the calorimeter and place the temperature probe into the solution. 2. Start the Logger Pro application. Open the folder Chemistry with Computers. Then open the file Endo-Exothermic. Using the Experimentmenu select Data Collection. Set the experiment length to 500 seconds. Set the sample rate to 0.5 samples/second. Oversampling should not be selected. 3. Double-click on the graph to select Graph Options. Set the time scale (x-axis) to 0 sec to 500 sec. the temperature scale (y-axis) to 0°C to 60°C. Enter a title for the graph. 4. Measure about 1 g of magnesium oxide to the nearest 0.1 mg on a weighing boat and record the mass in the data sheet. 5. Begin collecting data. The data should appear as a curve in the graph window. After you have at least thirty seconds of data displayed on the chart quickly add the magnesium oxide solid to the hydrochloric acid solution in the calorimeter. Quickly place the temperature probe back into the solution. 6. The cork should not be pushed in tightly over the calorimeter opening. Begin gently swirling the calorimeter for the length of the experiment. Set Set
