If a laboratory assistant prepared solutions of 0.8M, 0.6M, 0.4M, and 0.2Msucrose 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. This information would allow one to form the basis of his or her experiment in trying to determine the concentrations of the unlabeled solutions. The specifics of the experiment will be discussed along with the results one would expect from such an experiment. However, it is also important to know why these predictable results would occur. They will also be discussed. In conducting the experiment it would be necessary to obtain dialysis tubing. This would play the role of the semi-permeable membrane. This is important because without a semi-permeable membrane substances other than water, such as glucose, could exit the apparatus and throw off the results. Diffusion of the solutes would occur. Diffusion is the
