The effluent from an anaerobic digester is simulated as a mixture of 5 times 10^-4 M each of NaH_2 PO_4 and Na_2 HPO_4, and 6 times 10^-4 M each of NH_3, H_2 CO_3, and NaHCO_3. Identify the species that you think will be dominant in each acid/base group in the equilibrated solution. Write the TOTH equation for the system, using H_2 O, H^+, H_2 PO_4^-, NH_3, HCO_3^-, and Na^+ as components. Estimate the equilibrium pH, assuming ideal solute behavior. (You can sketch a log C-pH diagram if you'd like, but you need not do so to answer the question.)
