Potassium iodide solution is added to lead nitrate solution, and bright yellow lead iodide precipitates.
Potassium iodide solution is 0.1 M and lead nitrate solution is 0.01M.
The lead nitrate solution is about 350 ml in a 600ml beaker, and the KI sol'n is 200 ml in a 400ml beaker. Pour the potassium iodide sol'n into the lead nitrate.
Glasses and gloves. The finished demonstration is stirred and the precipitate and solution goes in the hazardous waste bucket.
