Use the systematic treatment of equilibrium to determine the pH and concentrations of species in 1.00 L of solution containing 0.065 mol citric acid (H3A), 0.025 mol 8-hydroxyquinoline (HB), and 0.040 mol KOH. Consider just acid-base chemistry. Ignore ion pairing and activity coefficients. Citric acid (H3A) is a triprotic acid with pKH3A = 3.128, pKH2A– = 4.761, and pKHA2– = 6.396. 8-Hydroxyquinoline (HB) is derived from the diprotic acid H2B with pKH2B = 4.94 and pKHB = 9.82.
