Unformatted text preview: ↔ Hg 2 2+ + SO 4 2SO 4 2+ H 2 O ↔ HSO 4+ OHH 2 O ↔ OH+ H + HSO 4+ H 2 O ↔ H 2 SO 4 + OH2. Charge balance: [ + ] = [  ] 2 [Hg 2 2+ ] + [H + ] = 2 [SO 4 2] + [HSO 4] + [OH] 3. Mass balance: [Hg 2 2+ ] = [SO 4 2] + [HSO 4] C (Hg 2 2+ ) = analytical concentration = [Hg 2 2+ ] 4. How many Ks will I have? K sp = [Hg 2 2+ ] [SO 4 2] → 7.4 x 107 K b = [HSO 4] [OH] / [SO 4 2] → K w /K b = K a K w = [OH] [H + ] → 1.0 x 1014 What happened to the 4 th equilibrium equation? 5. # of unknowns?; # of equations? 5 each Can I solve this problem with 5 unknowns and 5 equations?...
