Potassium iodide

Lead Nitrate - Potassium Iodide Lab

No votes yet

Purpose: The purpose of this lab was to try to get Pb I2 to filter out after combining Pb(NO3)2 and KI. We also wanted to further demonstrate what we did in class with limiting reagents. Materials: Lead (II) Nitrate Potassium Iodide 3 beakers Ring Stand Funnel Filter Paper Scale Water Stirring Rod Funnel clamp Wash Bottle Procedure: The first thing that we did was measure out 3.16g Pb(NO3)2 and 5.00 g of KI on the scale. Next we filled two of the beakers with 40 mL of water and poured the Pb(NO3)2 into one and the KI into the other. After dissolving them we then combined the two solutions into one beaker, which caused a thick, yellow substance to form.
