Based on the lab we worked on today, there are results for me to share. Firstly, I believe that the reason the lab took so long to complete was based on how fast the iodine entered the selectively permeable baggie. Since the bag was permeable, substances were able to enter the baggie. In this case, it was the iodine. Another thing I noticed was that the starch started turning purple from the bottom. The knot was half submerged, yet the smallest corner of the bag let in the iodine first. The molecules moved from a larger concentration are to a smaller area, because it moved from a 300 milliliter bearker into a tiny baggie corner.
