Definition of Bronsted Lowry Acid
Bronsted lowry acid can be defined as such a chemical species that has the 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. In short, Bronsted Lowry acid is known to be the proton donor whereas the Bronsted Lowry base is called as a proton acceptor.
