(a)
Interpretation:
Conjugate acid of
Concept Introduction:
Generally acid donates proton to form conjugate base. As donation of proton takes place, the conjugate base will have fewer hydrogen ions than that is present in acid. Base accepts protons to form conjugate acid. As proton is accepted, the conjugate acid will have more hydrogen ions than that of the base from which it is formed.
