The bronsted-lowry definition views an acid-base reaction as a proton transfer reaction.
Johannes Nicolaus Brnsted and Thomas Martin Lowry independently developed the Brnsted-Lowry theory, also known as the proton theory , which states that any compound that can transfer a proton to another compound is an acid, and the compound that accepts the proton is a base.
A proton is a nuclear particle with a unit positive electrical charge; it is denoted by the symbol H+. Similar to how a substance can only act as a base when a acid is present, a substance can only act as an acid when a base is present. Additionally, an acidic material transforms into a basic when it loses a proton.
In addition, when a basic substance obtains a proton, it generates an acid known as the conjugate acid of a base, and when an acidic substance loses a proton, it forms a base known as the conjugate base of an acid.
