Blog Revision of Diffusion and Osmosis Lab Quiz

The concentrations of the glucose inside and outside of the dialysis bag after 1 hour would be that the glucose would leave the bag due to the process of diffusion. Its the movement of solutes from areas of the high concentration to the low concentration. So, the concentrations of glucose inside and outside of the bag  will eventually become equal. The side of the diagram that would tend to move inside the bag would be the water because the concentration is greater because of the presence of glucose and starch. The starch stays inside of the bag because its a bigger molecule. Osmosis will then happen as the water moves into the bag until the concentration is the same on both sides of the membrane. This describes the lab that we did because the evidence that we collected in our group showed that the bag was clear because the water diffused into the bag. Also, the starch stayed in the bag because there was purple stuff at the bottom. The glucose test strips showed evidence supporting why the glucose left the bag.
