Hydronium Ion Definition Chemistry

The hydronium ion H 3 O + plays a central role in the acid-base chemistry of aqueous solutions. Johannes Nicolaus Brønsted (1879-1947) was a Danish physical chemist. Although he is now known mainly for his proton donor-acceptor theory of acids and bases (see his original article ), he published numerous earlier papers on chemical affinity, and.
