Diffusion in Liquids

In this classic experiment, from the Royal Society of Chemistry, students add potassium iodide and potassium manganate crystals to water to observe diffusion. The compounds diffuse through the water and upon meeting react leaving a yellow solid. The relative speed of diffusion can also be observed. The...
