Acid–base reaction

An acid–base reaction is a chemical reaction that occurs between an acid and a base. Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems.an acid is a substance with a pH less than 7, the base neutralises it

Quotes

• Perhaps the most important of all concepts related to electronegativity and polarity is that of acidity and basicity. We’ll soon see, in fact, that the acid–base behavior of organic molecules explains much of their chemistry.

• Acids differ in their ability to donate H⁺. Stronger acids, such as HCl, react almost completely with water, whereas weaker acids, such as acetic acid (CH₃CO₂H), react only slightly. The exact strength of a given acid HA in water solution is described using the acidity constant (K_a) for the acid dissociation equilibrium.
