Lab 5: Osmosis Purpose: The purpose of this lab is to familiarize you with osmosis and‚ specifically‚ what happens to cells when they are exposed to solutions of differing tonicities. Hypothesis: If we add higher concentrations of sugar to the dialysis tubing‚ then the net movement of coffee into the dialysis tubing will increase. Materials scale or balance 24" dialysis tubing 4 transfer pipets sugar scissors rubber bands four coffee cups - they need to be roughly the same size

G. Y. S. Period: 6 09/11/12 Osmosis Lab I. Objective: The purpose of this lab is to put the solutions in chronological order from least to most molarity. If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III. Table 1.1 | Initial | Final | % Change | A | 11.4 | 11.86 | 4.03% | B | 11.67 | 15.33 | 33.68% | C | 10.84 | 11.86 | 9.4% | D | 12.02 |

The movement of water down its osmotic gradient across a selectively permeable membrane is known as osmosis. The difference in the concentrations of solutes on either side of the membrane results in the establishment of an osmotic pressure. Water follows the direction of solutes‚ this means that in the event where there are more solutes outside the cell than there are inside the cell‚ water will move from the inside of the cell to the outside in order to establish water balance. When a cell is placed

Tide Graph: Life’s a Beach The ocean is something that has mesmerized me since I was young. I used to sit in the car at our local beach and stare into the open water and watch the waves roll by. My dad would patiently explain the dynamics of the ocean‚ making sure to warn me of the many hazards involved. Then I would watch as my father and all the “uncles” fish and surf. Although I spent a lot of time on my own‚ I enjoyed waiting‚ watching and observing. So when my brother mentioned that he found

Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change
