Diffusion and Osmosis Lab!


Lab day woo! We started out by filling a cup with distilled water, then added about 4mL of IKI(iodine) and tested the brownish solution with an indicator strip, coming up with a green result meaning there is no glucose. Then we took a dialysis tube, tied one end of it, and filled it with about 15mL of 15% glucose/1% starch solution. The glucose/starch solution was clear in color but tested positive for glucose(obviously). We took the tube and tied the other end of it and placed it in the IKI solution.
I wasn't here for the second day, so I didn't get to see the results sadly...
This lab was a lot of fun because we got to feel like scientists(:
