Definition of Conjugate Acid

Conjugate Acid is a part of Bronsted Lowry's theory of acids and bases and it can be defined as such a chemical species that has an ability to donate a hydrogen ion H+. In a reaction that is between an acid and a base, the acid is distinguished as it carries a positive charge i.e. it is a cation.


On the other hand, the conjugate base is that chemical species that accepts the H+ ion and it carries a negative charge and hence acts as an anion. The conjugates are formed when the acid loses a hydrogen ion and the base accepts a hydrogen ion.


The chemical reaction between an Acid and a Base:

Acid + Base ⇌ Conjugate Base + Conjugate Acid
