Introduction This report presents the study of the decomposition of the white product by electricity & decomposition of the product by heat. II. Procedures a. The Decomposition of the White Product by Electricity i. Team up with a different group and combine white solid product. This is done so there will be enough product to perform the lab activity. ii. Place a spatula full of white product on a white glass and add about 3-5 mL deionized water. Use a stirring rod to dissolve sample. iii. Make an electrolysis apparatus by attaching the 9-volt battery to the clips with newly clipped wire tips. The wires should be about 3” long. Not letting the tips touches each other, place them in the zinc iodide solution for 2-3 minutes. iv. First observe the anode and then the cathode. Identify each substance produce by the wire tips by comparing them visibly with the four standards. b. Decomposition of the White Product by Heat i. Transfer some of the white product to a large test tube. Gently heat white solid over Bunsen burner flame by moving test tube in and out of the flame for about a...
