In the conjugate base of ethane, the negative charge is borne by a carbon atom, while To clarify, HF acts as the acid (donates a proton), while F⁻ is its conjugate base (the remaining species after the proton donation). Definition: A conjugate acid-base pair consists of two species that transform into each other by the gain or loss of a proton. In the case of HF (hydrofluoric acid), once it donates the H+ ion/proton, it becomes F- (fluoride ion). Therefore, in this reaction, the pair formed is H F (the acid) and F − (the conjugate base). 1 – Acid-Base Definitions & Conjugate Acid-Base Pairs Acids and bases have been known for a long time.

Each Bronsted acid dissociates to release hydrogen ions and an HA/A-and HB+/B are called conjugate acid-base pairs (acid/base – acid component is written first) Differ from each other by a proton (H+) – the acid component of the pair has one more H+ To find the conjugate base of an acid, we need to understand that a conjugate base is what remains after an acid donates a proton (H+). Look at where the negative charge ends up in each conjugate base. A cation can be a conjugate acid, and an anion can be a conjugate base, depending on which substance is involved and which acid–base theory is used. In the case of HF (hydrofluoric acid), once it donates the H+ The conjugate base of an acid is formed by removing a proton (H+) from the acid.
