HandsOn 24 - Diffusion Chamber

Now carry out the diffusion experiment described below and compare the outcomes with the theory so far developed.


CAUTION: The chemicals used in this experiment are hazardous. Use plastic gloves and goggles and all standard precautions. In bending the tubes with a flame, use heat-resistant gloves. Carry out the experiment in a hood if facilities are available and few enough groups are doing the experiment. (With a large class and no use of hoods, the fumes from this experiment have been known to set off fire alarms.)

This experiment works best when carried out by three people. One person acts as timekeeper/data collector, while the other two handle the apparatus and read the measurements from the glass tube during the experiment. Materials for each group of three students:
