Proton donor

from Wikipedia, the free encyclopedia

Proton donor (Latin: donare = give or give ) is a chemical substance that transfers a proton to a reaction partner, the proton acceptor . Thus acids as proton donors and bases occur as proton. The process of proton transfer is called protolysis .

If an acid releases a proton, it becomes a proton acceptor and thus a base and, conversely, the base becomes an acid by taking up a proton. Systems of this kind are also called conjugated or corresponding acid-base pairs.

The terms introduced by Johannes Nicolaus Brønsted and Martin Lowry in 1923 expanded the acid-base definition .
