WebThe Glucose-testing strips indicate that glucose has been able to pass out of the tubing and into the external fluid. Thus proving the tubing allows movement in both directions. This inexpensive and simple experiment provides students with a clear visual result that effectively demonstrates how the size of a molecule can affect its ability to ...
WebAug 28, 2024 · It was concluded that the dialysis tubing doesn’t allow all kinds of substances to pass readily through the pores of its membrane. This means that it is selective in its permeability to substances. The dialysis tubing was permeable to glucose and iodine but not to starch. WebMar 30, 2024 · Yes because the glucose molecules were obviously smaller and were able to pass thru the dialysis bag. The starch molecuels were too big to pass thru the dialysis bag explaining the iodine (blue solution).
