NOTE: These labs are known for high failure rates. Therefore, if I show an example using data, a graph, etc… yours may be totally different depending upon mine and yours success with the lab. So don’t freak if your data is completely different from mine. And therefore the analysis of results sometimes may need to be answered differently since you base your analysis off your data and not mine. DISCLAMIER: DO NOT CHEAT! Data: Lab 1A - Table 1.1 Conte nts Initial Color Final Color Initial Presence of Glucose Final Presence of Glucose Bag 15% Glucose / 1% Starch Solution clear Dark blue + + Beaker H2O+I KI Orange to brown Orange to brown _ + Lab 1A Questions 1) Glucose is leaving the bag and Iodine-Potassium-Iodide is entering the bag. The change in color of the contents of the bag and the presence of glucose in the bag prove this. 2) In the results, the IKI moved from the beaker to the bag, this caused the change in the color of the bag. The IKI moved into the bag to make the concentrations outside the bag equal to inside the bag. The glucose solution moved out of the bag making glucose present in the beaker. The glucose moved to make the solute concentration inside and out of the bag equal. 3) If the initial and final percent concentration of glucose and IKI for in the bag and the beaker were given, they would show the differences and prove the movement of these substances to reach dynamic equilibrium. 4) Based on my observations, the smallest substance was the IKI molecule, then the glucose molecules, water molecules, membrane pore, and then the starch molecules being the largest. 5) If the experiment started with glucose and IKI inside the bag and starch in the beaker, the glucose and IKI would move out of the bag to make the concentrations equal, but the starch could not move into the bag because its molecules are too big to pass through the semipermeable membrane.
