Assertion : Weak acids have very strong conjugate bases while strong acids have conjugate bases.
Reason : Conjugate acid - base pair differ only by one proton.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Answer

B

Explanation

Strong acids such as perchloric acid `(HClO_(4))`, hydrochloric acid (HCl) give conjugate base ions `ClO_(4)^(-),Cl^(-)` which are much weaker bases acid is only partially dissociated in aqueous medium and thus the solution mainly contains undissociated acetic acid which proves that `CH_(3)COO^(-)` is stronger base than `H_(2)O`.
