You made a 9.5 buffer solution at 25 C by mixing and lysine (Lys) to give a solution that is 0.2 in total concentration of lysine. Lysine has three ionizable groups, with the following pka values pk, - 10.5 NH3 CH2 T 1 CH2 CH2 1 CH2 *HN-CH-C=0 pk, -90 O pk, -22 pK1 = 2.2 pK2 = 9.0 pK3 = 10.5 Answer the questions below with two significant figures. All questions pertain to 250C. Part A Calculate the concentration of Lys2+. Part B. Calculate the concentration of Lys+. Part C. Calculate the concentration of Lys(neutral). Part C. Calculate the concentration of Lys-. Part D. What is the proton concentration? Part E. What is the OH- concentration? Part F. What is the Na+ concentration?
