Acid-base reaction theories

Acid-base reaction theories are scientific theories that describe the mechanisms behind the reactions of acids and bases. These theories are fundamental to understanding many aspects of chemistry and biochemistry, including the behavior of amino acids, enzymes, and metabolic pathways.

Pronunciation

Acid: /ˈæsɪd/
Base: /beɪs/
Reaction: /riˈækʃən/
Theories: /ˈθɪəriːz/

Etymology

The term "acid" comes from the Latin acidus, meaning "sour". The term "base" comes from the Middle English base, meaning "low", in contrast to acids, which were thought to be "high" or "sharp". The term "reaction" comes from the Latin reactio, meaning "a response". The term "theory" comes from the Greek theoria, meaning "contemplation, speculation".
