noun
- 1. a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically, a corrosive or sour-tasting liquid of this kind. "traces of acid"
- 2. a molecule or other entity that can donate a proton or accept an electron pair in reactions.
adjective
- 1. containing acid or having the properties of an acid; having a pH of less than 7. "poor, acid soils"
- 2. sharp-tasting or sour: "acid fruit"
An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).

There are different ways of defining acids. A person referring to "an acid" is usually referring to an Arrhenius or Brønsted-Lowry acid. A Lewis acid is typically called a "Lewis acid." The reason for the differing definitions is that these different acids don't include the same set of molecules: 1. Arrhenius Acid: By this definition, an acid is a ...
These are examples of types of acids and specific acids: 1. Arrhenius acid 2. Monoprotic acid 3. Lewis acid 4. Hydrochloric acid 5. Sulfuric acid 6. Hydrofluoric acid 7. Acetic acid 8. Stomach acid (which contains hydrochloric acid) 9. Vinegar (which contains acetic acid) 10. Citric acid (found in citrus fruits)
Acids may be identified as either strong or weak based on how completely they dissociate into their ions in water. A strong acid, such as hydrochloric acid, completely dissociates into its ions in water. A weak acid only partly dissociates into its ions, so the solution contains water, ions, and the acid (e.g., acetic acid).
