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 any ionic compound that releases hydrogen ions (H+) in solution. Ionic compounds are molecules held together by ionic chemical bonds that result from the attraction of oppositely charged atoms, called ions. Article Summary: The pH scale is a measurement of the acidity or alkalinity of a solution. To understand the scale, it is important to first understand what acids and bases are. Acids, Bases, Buffers, and the pH Scale.
