Use the systematic treatment of equilibrium to determine the pH and concentrations of species in 1.00 L of solution contatining 0.070 lysine HL 0.055 mol aspartic acid H2A and 0.0080 mol NaOH. Consider just acid base chemistry. Ignore ion pairing and activity coefficients. Lysine (HL) is derived from the triprotic acid H3L2+ with pK of H3L2+=1.77, pKH2L+=9.07, and pKHL=10.82. Aspartic acid (H2A) is derived from the triprotic acod H3A+ with pKH3A+=1.990, pKH2A=3.900, and pKHA-=10.002
