Human serum albumin (HSA) has a molecular weight of 66,000 g/mol. One compartment contains a solution with HSA and the other compartment in the osmotic cell contains only an electrolyte solution. At a pH of 8 the net charge on HSA is -20. (a) The compartment that only has the electrolyte solution is maintained at a pH-8 with 1 M solution of NaOH. Find the concentration of Na+ and OH- in the HSA-containing compartment with a protein concentration of 40 mg/g-water. (b) What is the osmotic pressure at 298.15K in the cell in part (a)? (c) Compute the electrostatic potential difference between the two cells in part (a).
