base According to the Brønsted–Lowry theory (proposed in 1923 by both J. N. Brønsted in Copenhagen and T. M. Lowry in Cambridge, who were working independently of one another), a substance that in solution can bind and remove hydrogen ions or protons. The Lewis theory (proposed by G. N. Lewis, also in 1923) states that it is a substance that acts as an electron-pair donor. A base reacts with an acid to give a salt and water (a process called neutralization), and has a pH greater than 7.0.
