Conjugate acid-base pair differ by
- A electron
- B proton
- C neutron
- D hydroxyl group
Answer & Solution
Correct Answer
(B) proton
Step-by-step Solution
Detailed explanation
According to Bronsted-Lowry concept, after losing a proton, acids convert into conjugate base and after gaining a proton, bases convert into their conjugate acid, ie,
\(
\begin{array}{l}
\text {Acid }-\mathrm{H}^{+} \longrightarrow \text {conjugate base} \\
\text {Base }+\mathrm{H}^{+} \longrightarrow \text {conjugate acid}
\end{array}
\)
Thus, conjugate acid-base pair is differ by proton.
\(
\begin{array}{l}
\text {Acid }-\mathrm{H}^{+} \longrightarrow \text {conjugate base} \\
\text {Base }+\mathrm{H}^{+} \longrightarrow \text {conjugate acid}
\end{array}
\)
Thus, conjugate acid-base pair is differ by proton.
