A disk-diffusion test using E. coli gave the following results: Disinfectant Zone of inhibition (diameter in mm) A 15 B 2.0 C 10 D 5 In the table above, which compound was the most effective against E. coli? A) A B) B C) C D) D E) The answer cannot be determined based on the information provided.
You set up an experiment where you place a sealed (clamped) dialysis tube cell in a beaker of water. The solution in the dialysis tube cell is 25%NaCl solution and the solution in the beaker is 1%NaCl solution. The solvent for both is water. Before you place the tube in the cell, after it has been filled and clamped, you find the mass of the ‘cell’ after carefully drying off any water on the outside or on the clamps. You also find the mass of the cell after it has been placed in the beaker solution for 30 minutes after carefully drying off the outside of the ‘cell’ and clamps. The masses are in the table below. Mass in grams of dialysis tube cell Initial Mass 25.0g Final Mass after 30 minutes 28.7g Using this information, explain the difference in mass before and after submerging the cell in the beaker solution for 30 minutes.

Consider the two solutions separated by an ideal semipermeable membrane (permeable to water but impermeable to solute). Assuming complete dissociation of all the salts you can expect: a.) net water movement from side 1 to side 2 b.) net water movement from side 2 to side 1 c.) no net water movement
Inside a beaker, dialysis membrane A is filled with a 50% glucose solution and dialysis membrane B is filled with a 50% NaCl solution. Both bags are put into beakers containing 100% water. Which of the following choices is correct? (hint: the dialysis membrane is only permeable to water) a) For both solutions, it is isosmotic, and hypotonic so water flows into the membrane.b) For both solutions, it is isosmotic, and isotonic so there is not net flow of waterc) For both solutions, it is hyposmotic, and hypotonic so water flows into the membraned) For both solutions, it is hyperosmotic, and hypertonic so water flows into the membranee) For both solutions, it is hyposmotic, and hypertonic so water flows out of the membrane
A student designed an experiment to test whether different concentration gradients affect the rate of diffusion through dialysis tubing. Four different solutions (0% NaCl, 1% NaCl, 5% NaCl, and 10% NaCl) were tested under identical conditions. Twenty mL of each solution was placed into separate dialysis tubing that is permeable to Na+, Cl-, and water. Each bag was placed in a separate beaker and covered with distilled water. The concentration of NaCl in the water outside of each bag was measured at 40-second intervals. The graph below shows the results from the 5% bag: Concentration of NaCl Outside of Dialysis Bags Concentration of NaCl (mg/L) 400 320 240 160 80 0 40 80 Time(seconds) 120 5% Solution 160 a. Describe the process of diffusion through the dialysis tubing. b. If you were to design a different experiment testing rates of diffusion, identify experimental procedures. c. Analyze that data in the graph and describe the results. Provide reasoning to justify your answer. d.…
why does water move inward in a hypotonic solution?
The dialysis bag membrane in the figure is permeable to water and to the simple sugars only. The final solute concentration will: • Stay same without change • Reach equilibrium on both sides. • Sucrose concentration will be higher inside the bag. "Environment" 0.01 M sucrose 0.01 M glucose "Cell" • Glucose concentration will be higher inside the bag. 0.03 M sucrose 0.02 M glucose 0,01 M fructose • Fructose concentration will be higher inside the bag.
