Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline. Strong acids, such as sulfuric, phosphoric and hydrochloric acids also effect dehydration and condensation reactions.he Arrhenius definition defines acids as substances which increase the concentration of hydrogen ions (H +), or more accurately, hydronium ions (H 3 O +), when dissolved in water. The Broensted-BrÃ¸nsted lowry definition is an: expansion an acid is a substance which can act as a proton. donor
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 ...
