Diffusion 1.02

Experiment 1. Discussion

In order to turn the litmus blue, molecules of ammonia must have travelled from the cotton wool at one end of the tube to the litmus paper at the other end. This process of molecular movement is called DIFFUSION.

I Why is it unlikely that (a) air currents through the tube or (b) convection currents inside the tube could have distributed the ammonia ?

2 What influence on the rate of diffusion does the concentration of the source have in

this case?
