If a laboratory assistant prepared solutions of 0.8M, 0.6M, 0.4M, and 0.2M sucrose but forgot to label them there would be no need for him to panic. Knowing the principles of water movement through the processes of osmosis and diffusion, one can conduct a rather simple experiment to determine which flask contains which solution. According to the principles of osmosis, water typically moves from solutions of low solute concentration to areas of high solute concentration. …

…to determine which flask contains which solution. A simple but effective experiment could be conducted as well. The experiment would yield rather predictable results, that is, the 0.8M bag would gain the most mass in water while the other bags would gradually gain less water. Furthermore, knowing the characteristics of water flow in hypertonic and hypotonic solutions, which is the osmotic principle, one can understand why the results of this experiment are what they are.
