Lab 20A lodination of Acetone Concentration SJBoylan2018 RATIO METHOD TO DETERMINE REACTION RATE MODEL You add 10 mL of 4.0 M acetone, 10 mL of 1M hydrochloric acid and 20 mL of water to a 125 mL Erlenmeyer ask. You mix the solution. Then you add 10 mL of 0.0050 M iodine to the flask, mix the solution and start a timer. At time equals zero the color of the solution is straw yellow with a hint of orange. This yellow color is from the iodine. You pour the solution into a 200 mm test tube. You look down the top of the test tube to watch the color of the solution. After 251 seconds the solution turns clear. The clear color indicates that all the iodine has reacted to iodoacetone. Use the information from the above paragraph to fill in the diagram.
