Study Notes

Acid-Base Theory

A conjugate acid is the species that forms when a base accepts a proton (H+).
According to the Brønsted–Lowry theory, an acid is a species that donates a proton (H+).
A conjugate base is the species that forms when an acid donates a proton (H+).
A conjugate base of an acid can itself be acidic because it can still donate a proton, albeit less readily than the original acid.
In the context of the Brønsted–Lowry theory, a proton refers to a hydrogen ion (H+), which is a positively charged ion.
