This lab examined the effects of diffusion, specifically osmosis, in dialysis tubing model cells of different solute concentrations. In turn, this lab provides a model for what happens in living cells when osmosis occurs. For the lab three beakers were filled three quarters full with solution. One beaker contained water and the other two contained a water and sugar syrup solution. Three dialysis tubes were then filled with solution and placed into the beakers to create "model cells." The beaker with water contained a model cell filled with sugar syrup solution, and the two beakers with sugar syrup solution contained model cells filled with water and sugar syrup solution, respectively. The beakers were observed hourly for three hours.…show more content…
In their 2011 study, Jin et al. created a model to depict the "forward" osmosis (FO) of boron across a membrane. The motivation behind this experiment was to see how the model depicted the transport of boron and other contaminants across a membrane during osmosis (Jin et al., 2011). This knowledge is important because it provides a possible use of FO in water treatment, such as seawater desalination and wastewater reclamation (Jin et al, 2011). For this experiment, I predict that model cell one and model cell three will result in a change due to osmosis. First of all, I think that the water and syrup solution placed in water will result in water entering the water and syrup cell via osmosis. For model cell two, I believe the result will be no net movement between the outside sugar solution and the sugar solution within the cell. Lastly, for model cell three, I believe the result will be that water leaves the cell. Hypothesis: In this lab, osmosis will occur between the solutions of different concentrations, but not between the solutions of the same
