Example 8. The Arrhenius definition of an acid is an H+ producer … But carbon is a more polarizable atom (often said to be “softer”) than hydrogen, and this leads to some marked differences. After a Bronsted-Lowry acid donates a proton, it forms its conjugate base. Describe the acid-base behavior of amphiprotic substances. The Arrhenius definition of an acid is an H+ producer and the base is an OH- producer. An acid is a proton (hydrogen ion) donor. Acid–base reaction - Bronsted-Lowry, Definition, Chemistry: In order to resolve the various difficulties in the hydrogen–hydroxide ion definitions of acids and bases, a new, more generalized definition was proposed in 1923 almost simultaneously by J. Bronsted-Lowry theory, a theory stating that any compound that can transfer a proton to any other compound is an acid, and the compound that accepts the proton is a base. 22, 1879, Varde, Den. Organic Chemistry I (Cortes) 11: Bronsted Acid-Base Chemistry. Lewis called acids electrophilic.
