WebUsing the Brønsted-Lowry definition, an acid-base reaction is any reaction in which a proton is transferred from an acid to a base. We can use the Brønsted-Lowry definitions to discuss acid-base reactions in any solvent, as well as those that occur in the gas phase. Note that depending on your class—or textbook or teacher—non-hydroxide-contai… WebBrønsted Acid-Base Theory Brønsted argued that all acid-base reactions involve the transfer of an H + ion, or proton. Water reacts with itself, for example, by transferring an H + ion from one molecule to another to form an H 3 O + ion and an OH - ion. According to this theory, an acid is a "proton donor" and a base is a "proton acceptor."
