WebTo being the experiment each dialysis tubing was tied off at the bottom and filled with a sucrose solution. Bag A and Bag B were both filled with a 10mL 1% sucrose solution. Bag C was filled with a 10mL 25% sucrose solution and Bag D was filled with a 10mL 50% sucrose solution. Each bag had all the air pushed out of it and the open end was tied ... WebFeb 3, 2024 · What do your observations tell you about the presence of glucose starch and Iki in the dialysis bag and the beaker before and after the experiment? The results show that the water, glucose, and IKI molecules were small enough to pass through the selectively permeable membrane. The starch didn’t leave the beaker because its molecules were …
