This class practical shows that diffusion takes place in liquids. Students place colourless crystals of lead nitrate and potassium iodide at opposite sides of a petri dish of deionised water. As they dissolve and diffuse towards each other they form clouds of yellow lead iodide.
This practical activity takes around 30 minutes.
The demonstration Lab:Solid-solid reaction involves the same reaction but in the solid state.
