Chemist Johannes Bronsted and scientist Thomas Lowry proposed that an acid should be defined as a substance that can donate a proton, while a base...
The Brønsted-Lowry acid-base theory is still used extensively, but it is very restrictive as it focuses primarily on acids and bases acting as proton donors and acceptors. Sometimes conditions arise where the theory doesn’t necessarily fit, such as in solids and gases. In 1923, G.N. Le...
