WebThe Lewis concept is widely used in chemistry to explain the behavior of acids and bases in a variety of chemical reactions. For example, a Lewis acid can accept a pair of electrons from a Lewis base to form a new bond, or it can accept a pair of electrons from a molecule, such as a molecule of water, to form a hydrated complex. WebArrhenius theory, theory, introduced in 1887 by the Swedish scientist Svante Arrhenius, that acids are substances that dissociate in water to yield electrically charged atoms or molecules, called ions, one of which is a hydrogen ion (H+), and that bases ionize in water to yield hydroxide ions (OH−). It is now known that the hydrogen ion cannot exist alone in … dmからline 女から

"WebThe Lewis Acid definition is a broader one, so encompasses more compounds. A subset of these compounds would also qualify as Bronsted-Lowry Acids, since this definition is much more restrictive. There is no true definition of an acid; a chemical doesn't know if it is an acid or a base or neither. " - Explain lewis acid base theory
