protonutbytande
Protonutbytande is a term used in chemistry to describe a substance or material that can exchange protons (H+) with its surroundings. In practice, proton exchange occurs when ionizable groups on a molecule or solid surface gain or lose a proton as the environment’s pH or composition changes. Such materials may act as proton donors (acids) or proton acceptors (bases), and their protonation state influences properties like charge, solubility, and conductivity.
Common forms of protonutbytande substances include organic ion-exchange resins with acid or base functional groups, polymers
Applications span water treatment, acid–base buffering, catalysis, and energy technologies. In fuel cells and electrolyzers, protonutbytande
Terminology varies by field, but protonutbytande broadly covers materials and systems capable of reversible proton transfer.
