Students are often confused about how a solution can be "supersaturated". What does it mean that there is more than the maximum amount of solute dissolved under a given set of conditions? Crystalize your students' thoughts around these sometimes puzzling definitions by performing an easy demonstration with sodium acetate. Watch the video to see how to make supersaturated solution and observe the excess solute quickly come out of solution when a few small pieces of sodium acetate are introduced. Using PASCO sensors and data collection software you can even quantify the crystallization by monitoring the process with a Fast Response Temperature Probe.
