5. You have a dialysis bag containing 15-mL protein solution in0.20 M NaCl. a. Would it be more efficient to dialyse this solutionagainst i)one 2 L volume of buffer until equilibrium is reached, orto ii)dialyze the solution against one L buffer until equilibriumis reached, the remove the bag and dialyze against another one L ofbuffer til equilibrium is reached. Assume there is no volume changein the dialysis bag with dialysis. (1 pt) {type answer here } b.What is the concentration of NaCl left in the dialysis bag aftercondition i? What is the concentration of NaCl left in the dialysisbag after condition ii? (2 pts)
