Scoop a small amount of Pb(NO3)2 into the water at one side of the dish. Scoop a small amount of KI into the water directly opposite the Pb(NO3)2; A precipitate of PbI2 will form near the center of the dish. Demo Time: ~1 minute. Safety Pb(NO3)2 is toxic. Care should be taken to avoid breathing KI dust. Acknowledgment
The equation Pb(NO3)2 + 2 KI is the left side of the equation for the reaction of lead(II) nitrate and potassium iodide. The full equation is written as Pb(NO3)2 + 2KI = 2KNO3 + PbI2, representing the products of the reaction as potassium nitrate and lead(II) iodide.

Precipitation Reactions Precipitation reactions involve mixing two solutions of Water soluble salts, Aqueous Solutions (denoted “aq”), to form a solid salt. An example is the reaction between soluble Lead Nitrate, Pb(NO 3) 2 (aq), and Potassium Iodide, KI(aq), to form the insoluble salt Lead Iodide, PbI 2 (s); which
