3.Which bag from your experiment showed the least change in weight over time? Explain this result. 4.Explain why there was a difference in the initial and final rates of osmosis for the 4 bags in this experiment. 5.What molecule was moving across the dialysis membrane to produce the weight changes observed in the bags? 6.What happened to your rates of osmosis over time in the experiment, why did they change? 7.Based upon your results and the graph you made above, what do you predict is the composition of the fluid inside the unknown bag and the beaker? 8.Based upon your results from this experiment, which molecule was able to pass across the membrane? Explain why this molecule was able to move. 9.Will the permeable solute completely diffuse out of the bag into the water? Explain. 10. How do these dialysis bags and real cell membranes differ in their selective permeability? 9
