In this lab experience, students carry out an investigation to record the heating and cooling curves of an organic solid. Students should observe that the hot water fizzes the carbon dioxide source much more vigorously than the cool water sample. Therefore, the increasing temps in the water much more readily release carbon dioxide. Their graphical plot should clearly identify this trend.
