	4. Add 50 mL of Solution A to a clean beaker fitted with a stir bar. Next add 50 mL of Solution B and let solutions mix thoroughly. Once complete, add 50 mL of Solution C and let reaction stir. Upon addition of the final solution, bubbles should appear. The solution will turn yellow then blue, then colorless. This reaction will oscillate for 5-10 minutes.		4.

1. Solution A: Prepare 100 mL of 9% H2O2 by diluting 30 mL of 30% H2O2 with 70 mL of deionized H2O.

2. Solution B: Prepare an acidified 0.2 M KIO3 solution by adding 10 mL of 1.0 M H2SO4 to 80 mL of deionized water. Dissolve 4.3 g KIO3 in this solution and dilute to 100 mL.

3. Solution C: Prepare starch solution by dissolving 0.1 g of soluble starch in 90 mL of boiling deionized water. When cool, add 1.5 g malonic acid, 0.4 g MnSO4·H2O, stir and dilute to 100 mL.

4. Add 50 mL of Solution A to a clean beaker fitted with a stir bar. Next add 50 mL of Solution B and let solutions mix thoroughly. Once complete, add 50 mL of Solution C and let reaction stir. Upon addition of the final solution, bubbles should appear. The solution will turn yellow then blue, then colorless. This reaction will oscillate for 5-10 minutes.
