In which of the following titrations would the solution be neutral at the equivalence point?
Select one:
a. NH3 titrated with HCl
b. Sr(OH)2 titrated with H3PO4
c. HOCl titrated with Ba(OH)2
d. CH3COOH titrated with NaOH
e. HClO4 titrated with KOH
HClO4 + KOH ------------> KClO4 + H2O
HClO4 = strong acid
KOH = strong base
salt formed by strong acid and strong base gives neutral salt.
e. HClO4 titrated with KOH

In which of the following titrations would the solution be neutral at the equivalence point? [Hint: For a neutral equivalence point, we need both a strong acid and a strong base as analyte and titrant, respectively.] HOCl titrated with Ba(OH)2 CH3COOH titrated with NaOH HClO4 titrated with KOH Sr(OH)2 titrated with H3PO4 NH3 titrated with HCl
