Proton transfer – basic principles
How it works
In a proton transfer (acid-base reaction according to Brønsted), an acid gives a proton (H⁺) to a base. The acid becomes the conjugate base, the base becomes the conjugate acid. Typical examples are reactions between hydrochloric acid and water or ammonia and water. The direction of proton transfer depends on the strength of the acids and bases. Proton transfers are central to many chemical processes, e.g. in biological systems and technical applications.
Note
In a proton transfer, an acid gives a proton (H⁺) to a base; conjugate acid-base pairs are formed.

An example
What role does ammonia (NH₃) take on in the reaction with water?
Ammonia acts as a base because it accepts a proton from water. According to Brønsted, a base is a proton acceptor.
