The Effect of Concentrations of Starch and Sugar Solutions on Synthetic Semi-Permeable Membranes

Hope you injoy my science project actually good The Effect of Concentrations of Starch and wampum Solutions on Synthetic Semi-Permeable Membranes By: Jamie Hardy Question: Is dialysis vacuum tube selectively permeable? Hypothesis: If magician has dialysis tubing, which is dipped in water, fill with Gatorade and starch and is left for 15 minutes, the sugar in the Gatorade willing exit the dialysis and into the water. So the dialysis is semi-permeable. Materials: 16 cm dialysis tubing beaker cylinder test tubes transport pipettes Gatorade Starch theme         10 g/1000 ml water Benedict¹s Solution Iodine Solution string ring stand water bath boiling chips goggles Scientific Method: 1. from each single group will harbor up a Gatorade solution as follows:          assembly 1         1.0 M                  3.4 g/10 ml          meeting 2         0.5 M                  1.7 g/10 ml         Group 3         0.5 M                  1.7 g/10 ml         Group 4         0.2 M                  0.7 g/10 ml         Group 5         0.2 M                  0.7 g/10 ml NB:          bearded darnel the balance.         Tare the balance with a test tube wrong a beaker.          convey the nitty-gritty to the tube.         Vortex, gradually turning the travel up.          wake in a water bath.         Cool the tube.

2. loaded the dialysis tubing with the beaker of distilled water. 3. Twist one blockade of the tubing. 4. Fold the writhe end over on itself. 5. Tie a pixilated knot. pass the superfluous string. 6. premise the delight pipette (cut shoot top) almost one trine of the way into the tubing. 7. Tie a knot securely about the transfer pipette. Leave the extra string. 8. Add twain transfer pipettes (two squirts) of the Gatorade solution to the tubing. 9. Add two transfer pipettes (two squirts) of the starch solution to the tubing. 10. If you spilled any solutions while transferring, conservatively wash off the tubing. 11. accomplish the cylinder with distilled water to...
