3. Bulk transport across a membrane is illustrated in the below diagrams. Evaluate the diagrams; A a. What are the processes taking place in figure A and figure B. Be sure to explain the steps /4 4. Buffers are important to maintaining pH in a system. This is usually done with weak acids, weak bases, or a mixture of the two. Below is the chemical equation for a buffer solution in water, NH3+H3O+NH4++H2O a. Which direction would be favoured if we added HCl ? How would that work to maintain the pH of the system? /2 5. You are performing an experiment to look at osmosis across a semipermeable membrane. The internal environment of the dialysis tube has a 5% concentration of dissolved salt. The tube is then placed in a beaker containing pure water. You return a. What was the condition of the external environment in respect to the dialysis tube? /1 b. Which direction do you expect osmosis to flow? And do you expect the dialysis tube to be intact? /2 c. How can this information be important to medical professionals /2 3.
