Today we will do a Double Displacement Reaction. For this we need crystals of Potassium Iodide, crystals of Lead Acetate, two empty beakers and a conical flask filled with water. First we will prepare a solution of Lead Acetate. For this we will place a few crystals of Lead Acetate in an empty beaker. Then we pour some water and stir until the crystals dissolve. This will be a saturated solution of Lead Acetate. Similarly, we will also prepare of solution of Potassium Iodide. Place some crystals into an empty beaker, add some water and stir to make a solution of Potassium Iodide. The Potassium Iodide solution will be transparent like water, while the Lead Acetate solution will be milky in color. 
Now add Lead Acetate solution into the Potassium Iodide solution. Immediately a reaction will take place and you will see a very beautiful yellow precipitate. Here you will see two distinct layers. The lower layer will be the thick precipitate of Lead Iodide. The above floating liquid layer will be Potassium Acetate.
