Given that the final heights (and volumes) are the same for the water and test solution, what can you conclude about the amount of solutes in these two solutions? B. Explain your reasoning. Include where water travels and why. [2] As discussed in the Background material, water is an important biological macromolecule. A. Do you expect water to continue to flow across the semipermeable; lipid bilayer after osmotic equilibrium is reached? B. Why or why not? Include where water travels and why. Procedure II - Test Solution 2: Guanine solution – KNOWN Concentrations Solution Compound mMolar Concentration (mmol/L) solution 2 guanine 0.170 Complete the tables and questions below using your data and information found under the Background tab Data Table II Note: Difference in Final Volumes = Final Volume of Test Sol - Final Volume of Water 2 TableTop Science – All Rights Reserved 3 TableTop Science – All Rights Reserved Trial Starting Volume of Test Solution GUANINE (L) Starting Volume of Water (L) Final Volume of Test Solution GUANINE (L) Final Volume of Water (L) Difference in Final Volumes (L) 1 1.28 2 1.28 Observations and Questions [3] A. Why did the height (and volume) change in the test solution? B. What is the basis for the increase in the volume in the test solution? Include where water travels and why. [4] A. What do you think would happen if both starting volumes were the same? B. Test your hypothesis by doing a data run. Explain your observation. Include where water travels and why. [5] Why is the difference in final volumes the same for both trials? Include where water travels and why. Procedure III - Test Solution 3: Cytochrome C solution – UNKNOWN concentrations Solution Compound mMolar Concentration (mmol/L) solution 3 cytochrome c to be determined Complete the table and questions below using your data and information found under the Background tab (see the Summary of Needed Formulas section) and Activity Form tab Data Table III Note: Difference in Final Volumes = Final Volume of Test Sol - Final Volume of Water 4 TableTop Science – All Rights Reserved 5 TableTop Science – All Rights Reserved Trial Starting Volume of Test Solution CYTOCHROME C (L) Starting Volume of Water (L) Final Volume of Test Solution CYTOCHROME C (L) Final Volume of Water (L) Difference in Final Volumes (L) 1 1.28 2 1.28 Observations and Questions [6] A. Based on your data and observations from procedure II and procedure III, which solution, has the highest concentration? Guinine or Cytochrome C? B. Explain your answer. Include where water travels and why. [7] Concentration Calculation: Using your Trial 1 data from procedure II and procedure III, calculate the concentration of the cytochrome c solution. Hint: See the Summary of Needed Formulas section under the Background tab and information found under the Activity Form tab.
