=== Definisi proton (Brønsted-Lowry) ===
 
TheDefinisi Brønsted-Lowry definition, formulateddirumuskeun independentlysacara bymandiri itsku two proponentsmasing-masing [[Johannes Nicolaus Brønsted]] andjeung [[Martin Lowry]] intaun [[1923]], revolves around an [[acid]]'s ability to donate [[proton (physics)|protons]] (H<sup>+</sup>) to another compound, called a [[Base (chemistry)|base]], in a chemical reaction.

It may be more intuitive to define the stronger of two acids as the one which reacts more completely with a common base. The following shows that this definition gives the same result. Compare the reactions of the two acids HX and HY with the same base Z<sup>-</sup> (in a mixture containing all these species):
