What is the Lewis definition of an acid or a base? In this theory an acid is defined as an electron acceptor and a base is defined as an electron donor. What is the difference between acid and Lewis acid? An acid can be any liquid with a pH less than 7, whereas a Lewis acid spec...

Lewis acid-base concept 酸碱电子理论 酸碱电子理论（the electronic theory of acid and alkali），也称广义酸碱理论、路易斯（lewis）酸碱理论，是1923年美国物理化学家吉尔伯特·牛顿·路易斯（Lewis G N）提出的一种酸碱理论
Gilbert N. Lewis, an American physical chemist, put out the Lewis acid-base hypothesis. According to the electronic theory of acids and bases, all molecules, ions, and groups of atoms that can accept electron pairs are referred to as acids, and all molecules, ions, and groups of atoms tha...

The Bronsted-Lowry theory of acids and bases describes an acid as a substance that donates hydrogen ions (protons) by dissociating covalent "H-X" bonds. A base here is a substance that accepts hydrogen ions to form new "H-X" bonds. The Lewis theory is different, in that an electr...
