Osmosis Lab assignment

Osmosis Lab assignment Words: 182

At the concentration 0. 2 M sucrose, the potato cylinders absorbed water, although not as much as when they were put in distilled water. This was because the solutions were hypotonic, I. E. They had a low concentration of solute, in this case sucrose, and a higher concentration of water same. This was because this was an isotonic solution compared to the potato cylinders. Isotonic solutions are solutions that have reached equilibrium, meaning the amount of water and sucrose was the same in the solution and inside the potato cylinders (Ward).

Other errors were probably because the amount of elution used (10 CM) wasn’t enough. If the volume of the solution is increased, it will show more changes as it will cover the potato cylinder better.
