WebLewis concept of acids and base. In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons. A Lewis acid is therefore any substance, such as the H + ion, that can accept a pair of non-bonding electrons. In other words, a Lewis acid is an electron-pair acceptor. Limitations of Lewis concept: 1.
