WebThe Brønsted-Lowry definition: 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 ...
