2. Place a few drops of iodine solution on each food. 3. Make observations immediately. 4. Wait a few more minutes and note any other changes. Observations Complete the chart below using the food your group has compiled. When drops of iodine solution are applied to a food containing starch, the solution will turn dark blue, purple, or blackish. Data table: Food product Description before testing Description after testing Conclusion: are complex sugars present? 1. 2. 3. 4. 5. 6.
1 To test for starch: A standard test for starch uses iodine. 2  Because iodine is not very soluble in water the first step is to form an iodine reagent by dissolving iodine in water in the presence of potassium iodide, resulting in a linear triiodide ion complex-which is soluble and yellow/orange in colour. Lugol's Solution: An example of an iodine-based product that has been widely used in medicine is Lugol's iodine (developed by French physician Jean Guillaume Auguste Lugol in 1829). 2  This consists of 5 g iodine (I 2), 10 g potassium iodide (KI) and enough distilled water to form a brown solution total volume of 100 mL.
