Acid

An acid (often represented by the generic formula HA) is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a pH of less than 7.0.

That approximates the modern definition of Brønsted and Lowry, who defined an acid as a compound which donates a hydrogen ion (H+) to another compound (called a base).

Common examples include acetic acid (in vinegar) and sulfuric acid (used in car batteries)..
