Explain with an activity diffusion of liquids?
Answers
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.

Explanation:
Use paper towels as a permeable membrane to demonstrate that small molecules can diffuse across a barrier from one liquid to another. Fill a jar with water and cover the opening with a paper towel in such a way that the center of the paper towel hangs down into the water. Put food coloring into the water that fills the paper towel and observe as the color diffuses through the barrier. Perform the experiment at varying temperatures to show how temperature affects diffusion.
