Answer to Question #209187 in General Chemistry for hayrunisa

Question

Explain which is the stronger acid

a)HNO₃ or HClO₄

b) CH₂FCOOH and CH₂BrCOOH

Answer 1

Answer:-

a)

HClO₄ is more acidic than HNO₃

To compare the acidic strength of any acid, we compare the stability of the conjugate base or the anion formed after loosing the acidic hydrogen. In the case of HClO4 there are 4 identical resonating structures which stabilizes the conjugate base and hence increases it's stability.

b)CH₂FCOOH is more acidic , as due to Electronegativity
