An '''acid''' is a [[molecule]] that creates H<sup>+</sup> and H<sub>3</sub>O<sup>+</sup> ions in water (according to the Arrhenius definition), that donates H<sup>+</sup> [[ions]] ([[proton]]s) in a chemical reaction (according to the [[Bronsted-Lowry theory|Bronsted-Lowry]] definition), or that accepts an electron pair in a reaction(according to the Lewis definition). Acids taste sour (although, in a laboratory, '''never''' taste an acid; they can be highly corrosive) and turn blue [[litmus paper]] red; they have pH values of less than 7. Acids are covalent compounds, but when dissolved in [[water]], they will conduct electricity. When an Arrhenius acid is put into water, it will loose its H<sup>+</sup>, a process called aqueous dissociation. [[Strong acid]]s are those that completely give up their protons in solution, whereas [[weak acid]]s reach an equilibrium concentration of H<sup>+</sup> in solution. Many [[organic molecule]]s that play important roles in biological processes are also acids, such as [[amino acid]]s and [[carboxylic acid]]s.
