Acid, any substance that in water solution tastes sour, changes the color of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).
General properties of acids and bases are described. Arrhenius's definitions and nomenclature of Arrhenius's acids and bases are also presented.
Hydrochloric acid (in beaker) reacting with ammonia fumes to produce ammonium chloride (white smoke). Acids can be dangerous: The holes in the paper were made by a solution with 98% sulfuric acid. An acid is a type of chemical compound. The definition of an acid has changed as people discovered more about chemistry. Acids were originally grouped together by their properties: they taste sour ...

The ACID properties, in totality, provide a mechanism to ensure the correctness and consistency of a database in a way such that each transaction is a group of operations that acts as a single unit, produces consistent results, acts in isolation from other operations, and updates that it makes are durably stored. 1. Data Integrity and Consistency
