Osmosis lab

We filled 2 sections of dialysis tubing with distilled water, 1 with 15% sucrose and distilled water, and 1 with 30% sucrose and distilled water. Then we put one of each in beakers containing distilled water and 1 tubing filled with distilled water was put in water containing 30% sucrose. Then we weighed them every ten minutes.

The first one, which was filled with destilled water and was put in distilled water, just about stayed the same. The second one, which was containing 15% sucrose and distilled water and was put in distilled water, slowly gained mass. The third one which was containing 30% sucrose and water was put in distilled water, went up greater than the last. The fourth one, which was containing distilled water was put in 30% sucrose and water, decreased.

The sucrose could not go through the dialysis tubing but the water could, so the sucrose sucked in water causing the second and third ones to increase and causing the last one to decrease.
