proton donor
Releases hydrogen ions
A proton donor is a substance that releases hydrogen ions (protons) to another substance in a chemical reaction.
In acid-base chemistry, acids are defined as proton donors: Hydrochloric acid acts as a proton donor when dissolved in water.
The concept is central to the Brønsted-Lowry definition of acids and bases.
