1. Place 5 mL of starch solution in each of 2 test tubes. 2. Heat the test tubes to boiling and add to 1 mL of saliva, Cool and then continue heating but keep the test tube in a water bath at temperature of 60oC 3. At 5 minutes interval for 30 minutes take a drop of the reaction mixture from each test tube and test with Iodine solution (use a spot plate for the test and stir the contents of the test tube before taking a drop). Tabulate the results. 4. What would be the color of saliva extract with iodine in 3, 6, 9,12,15,and 18 minutes
