DIFFUSION REACTION: PRECIPITATING LEAD IODIDE
Reaction of Potassium Iodide with Lead Nitrate
A thin pool of lead(II) nitrate solution touches a thin pool of potassium iodide solution. Lead(II) iodide solid is slowly formed at a rate which is controlled by the rate of diffusion of lead(II) ions into the potassium iodide solution.
