What Is Starch? -is a polysaccharide found in plants. -made up of amylopectin and amylose (polymers of glucose). -a polymer of approximately 600 glucose units in an unbranched coiled chain. -formed by the plant and deposited into organelles known as amyloplasts. -through dehydration synthesis, granules of starch are formed within the amyloplasts. -a quality in many paper products is strength; a way to increase dry strength is to add starch. Purpose In order to determine if various solutions contain starch, each 1 ml solution will be given 1 to 2 drops of iodine I 2 KI and observed to see if the solution changes to a blue-black color. There will also be two additional control groups: one positive control and one negative control. Scientific Hypothesis When iodine I 2 KI is added, solutions containing starch will turn a blue-black color while solutions not containing starch will not. Null Hypothesis When iodine I 2 KI is added, solutions containing starch will not turn a blue-black color and solutions not containing starch will do the same. Predictions
