In the Brönsted definition, an acid isa substance that donates a proton in any type of reaction. The mostgeneral definition, due to G.N. Lewis, classifies any chemical speciescapable of accepting an electron pair as an acid.Acid dissociation constant (K a )* - The equilibrium constant ...
Arrhenius Acid: By this definition, an acid is a substance that increases the concentration of hydronium ions (H3O+) when added to water. You might also consider increasing the concentration of hydrogen ion (H+) as an alternative. Brønsted-Lowry Acid: By this definition, an acid is a mat...

Generally, the Lewis definition of acids and bases is the most useful because it is the most inclusive of the three definitions. For example, the Brnsted-Lowry definition of an acid includes HF but not BH3, which doesn't lose a proton when attached by the lone pairs on a Lewis base. ...

Definition of Strong Acids In chemical terms, a strong acid is a species that completely dissociates in water to produce a high concentration of hydrogen ions. This means that strong acids fully break down into their constituent ions, releasing all their hydrogen ions (H+) into the solution. ...
