Perchloric acid is Very strong acid
Acetic acid is weak acid
In presence of very strong acid like pechloric acid
acetic acid bahaves as a base and accepts a proton(H+) from
perchloric acid and forms CH3COOH<2+
Non aqaous titrations are used to titrate the samples
which are very weak bases or salts of weak bases.So in our
titration we take a weak base sample in a titration vessel.

By taking protons from perchloric acid, acetic acid behaves
like a strong acid in presence of a weak base. So reaction
occurs between strong acid and a weak base.
Role of acetic acid:
1.In presence of strong perchloric acid it behaves like a
base and accepts protons.
2.In presence of weak base it behaves as a strong acid and
donates protons to weak base.Protons transfer from
perchloric acid to weak base through acetic acid.

Perchloric acid-------->acetic acid--------->weak base
Finally it is strong acid weak base titration but not acid
acid titration.
