Osmosis with the Potato Cylinders in Different Concentrations of Solutes INTRODUCTION The intention or purpose behind this experiment is Osmosis. Osmosis is essentially a form of diffusion through which water diffuses between/across/through a selectively permeable membrane from an area of higher concentration to an area of lower concentration. When molecules in elevated concentrations are too big to cross through the membrane this is the type of diffusion that typically takes place. When referring to a hypotonic solution, it means concentration of a certain substance is a little too big inside of a cell; cell therefore collects water to thoroughly mix this concentration. However, when referring to a hypertonic solution, the concentration of a given substance is too large inside the solution as opposed to inside of the cell; the cell will then have to lose water in order to maximize the concentration of the given substance.…show more content…
Osmolarity simply means the measure of concentration of a certain substance (that will have a difficult time diffusing across the membrane) in a given solution or inside the cell membrane. By recording the percent change in mass of the different potato tubings and finding when exactly the percent change in mass is zero we can determine osmolarity. Now, the concentration of a particular given substance is similar for both sides of the cell membrane. HYPOTHESIS: My team and I hypothesized that sugar's (sucrose) osmolarity inside of the potato tubing will fall between 0.3 M and 0.5 M. In essence, we were hypothesizing that mixtures or solutions of sugar (sucrose) between 0.0 (H2O) until 0.3 will lean more to be hypotonic and solution between 0.4 until 0.6 will most likely be hypertonic.
