Interpretation:
The graph for the titration of tetrabasic base with strong acid, 50.0 mL of 0.0200 M sodium pyrophosphate(Na4P2O7) with 0.100 M HClO4 has to be plotted.
Concept Introduction:-
Titration of tetrabasic base with strong acid:
When a strong acid is titrated against tetrabasic base, there is an equivalence or stoichiometric point, when an H+ is dissociated then there are multiple equivalence points. The equivalence point will occur when the moles of the strong acid added to same amount of the moles of weak base present. However, when a weak polyprotic acid is titrated. Therefore, the number of equivalence points depends on the number of H+ atoms that can be removed from the molecule.
Spreadsheet Equation for titration of titration of tetrabasic base with strong acid:
ϕ≡CaVaCbVb=αBH++2αBH22++3αBH44++4αBH44++[H+]-[OH-]Cb1-[H+]-[OH-]Ca
Where,
Ca=initial concentration
Cb=final concentration
Va=volume of the acid
Vb= volume of the base
αA =acid dissociation constant.
ϕ =fraction way to equivalence point.
