acid–base reaction
Let an agent explain acid-base reactions under the major theories, relay examples, equilibria and applications from chemistry references, and distinguish acid-base reactions from redox and other reaction types.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain acid-base reactions under the major theories, relay examples, equilibria and applications from chemistry references, and distinguish acid-base reactions from redox and other reaction types.
A chemical reaction between an acid and a base, described by Arrhenius as forming water and a salt, by Bronsted and Lowry as proton transfer from a proton donor to an acceptor, and by Lewis as electron pair donation, including neutralisation, autoprotolysis of solvents such as water, and proton transport by the Grotthuss mechanism; acid-base reactions underlie titration, buffering, biochemistry and industrial chemistry.
What it is for: Not applicable; a class of chemical reactions.
It can be explain the theories; relay examples and equilibria; describe applications; distinguish from other reactions.
Distinguishing features
Proton transfer
Conjugate pairs
Equilibrium constants
Multiple theories
What it looks like
Not a visible object; often observed as colour change with indicators or heat release.
Physical character
water ion product: 1.0e-14 at 25 C - autoprotolysis
strong acid-base neutralisation enthalpy: about -57 kJ/mol
How it is recognised
Proton or electron pair transfer between acid and base
Neutralisation, autoprotolysis, Grotthuss proton hopping, Lewis acid-base reactions
Redox reactions transfer electrons; precipitation reactions form solids
