Write an equation for the titration of tetrabasic base with strong acid (B + H+ → → → → BH4+4. You can do this by inspection of Table 10-5 or you can derive it from the charge balance for the titration reaction. Graph the titration of 50.0 mL of 0.0200 M sodium pyrophosphate (Na4P2O7) with 0.100 M HClO4. Pyrophosphate is the anion of pyrophosphoric acid.
