Objective The objective of this laboratory experiment was to observe a process  called diffusion, which is the net movement of molecules or ions from a  region of higher concentration to a region of lower concentration until they  are evenly distributed (in equilibrium). For this laboratory experiment, two  different colored solids (potassium permanganate and methylene blue) were  placed in water (liquid phase) and an agar-coated petri dish (solid phase).  The rates of diffusion were measured, compared, and analyzed.  1. Forceps were used to carefully place a large crystal of potassium  permanganate into a test tube filled with water.  2. The test tube was placed in a test tube rack, and left undisturbed.  3. The diffusion of the crystal material through the water was observed  at fifteen minute intervals for approximately one hour.  *Then, steps 1-3 were repeated in a separate test tube, carefully placing a  large crystal of methylene blue instead of potassium permanganate.
