The shape of a titration curve depends on the ionization constants of the acid and base and their
concentrations. The example given above is for a weak acid and strong base. The equivalence point
is defined as the point where the amount of base added is equal to the original amount of acid in the
solution. Therefore, at the equivalence point, the number of moles of base added equals the number
of moles of acid originally present in the solution being titrated. After determining the equivalence
point, the concentration of the basic solution can be easily calculated with the titration formula
(when the stoichiometry of acid and base is 1:1):
Molarity of acid (mol/L) x Volume of acid = Molarity of base (mol/L) x Volume of base
Macid X Vacid = Mbase X Vbase
moles of acid in original solution = moles of base added
Concentration of base (mol/L) or [base] =

The shape of a titration curve depends on the ionization constants of the acid and base and their

is defined as the point where the amount of base added is equal to the original amount of acid in the

of moles of acid originally present in the solution being titrated. After determining the equivalence
point, the concentration of the basic solution can be easily calculated with the titration formula
(when the stoichiometry of acid and base is 1:1):
Molarity of acid (mol/L) x Volume of acid = Molarity of base (mol/L) x Volume of base
Macid X Vacid = Mbase X Vbase
moles of acid in original solution = moles of base added
Concentration of base (mol/L) or [base] =
