1. Arrhenius definition. : An acid is a substance that dissociates in water to produce H+ ions (protons), and a base is a substance that dissociates in water to produce OHâions (hydroxide); an acid-base reaction involves the reaction of a proton with the hydroxide ion to form water. 2.
An acid is a molecule or ion capable of donating a hydron, or, alternatively, capable of forming a covalent bond with an electron pair. The first category of acids is the proton donors or BrÃ¸nsted acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. BrÃ¸nsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A BrÃ¸nsted or Arrhenius acid usually contains a hydrogen atom bonded to a chemical ...
