perchloric acid&glacal acetic acid both are acids but
reaction is complete in volumetric titrations.how?
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.
