Because of the very large range of acid strengths ( greater than 10 40), a logarithmic scale of acidity ( pK a) is normally employed.Stronger acids have smaller or more negative pK a values than do weaker acids.
The reaction of an acid and a base is called a neutralization reaction. Although acids and bases have their own unique chemistries, the acid and base cancel each other’s chemistry to produce a rather innocuous substance—water. In fact, the general reaction between an acid and a base is. acid + base → water + salt Every ion dissociation that involves a hydrogen or hydroxide ion could be considered an acid- base reaction. Just as with the Arrhenius definition, all the familiar materials we call acids are also acids in the Lowry - Br¯nsted model. The G.N. Lewis (1923) idea of acids and bases is broader than the Lowry - Br¯nsted model.
