A conjugate acid-base pair consists of two species that differ by only one proton (H⁺).
When a base accepts a proton, it forms its conjugate acid.
When an acid donates a proton, it forms its conjugate base.
Example:
Consider the reaction of ammonia (NH₃) with water (H₂O):
NH₃ + H₂O ⇌ NH₄⁺ + OH⁻
Ammonia (NH₃) acts as a base and accepts a proton from water. Its conjugate acid* is ammonium ion (NH₄⁺).
Water (H₂O) acts as an acid and donates a proton to ammonia. Its conjugate base* is hydroxide ion (OH⁻).
Therefore, (NH₃ / NH₄⁺) and (H₂O / OH⁻) are two conjugate acid-base pairs in this reaction.
