   Acid
   A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly.

   Acid
   There are three definitions - Arrhenius, Bronsted, and Lewis Acids. In the Lewis conception, which is the most general and useful, an acid is essentially any compound that needs electrons, and a base is basically any compound that wants to give them away.

   Acid
   An acid is a chemical compound that reacts with metals to form salts by releasing hydrogen. All acids contain hydrogen, some also contain oxygen and these are called oxy-acids. Varying amounts of oxygen in an acid are reflected in its name ending -ous or -ic, and the salts formed from such acids are similarly named ending in -ite and -ate.

   Acid
   An Acid is a substance containing hydrogen in its molecules (or ions) that it can release as H⁺ ions. The Bronsted-Lowry definition of an acid is that it is a 'proton donor'. By strength of an acid is meant the tendency with which it will donate H⁺ ions; the stronger the acid the more readily it will donate H⁺ ions. The terms 'strength' and 'concentration' with regard to acids must not be confused; a concentrated solution of a weak acid is still a weak acid.
   Hydrochloric acid, HCl, is an example of a strong monobasic acid; it is essentially completely ionised in aqueous solution.
   HCl_(aq) + H₂O_(aq) ® H₃O⁺_(aq) + Cl^-_(aq)
   The organic acid, ethanoic acid, CH₃COOH, is an example of a weak monobasic acid; it is partially ionised in aqueous solution, an equilibrium existing between the acid and its conjugate base.
   CH₃COOH_(aq) + H₂O_(l) = H₃O⁺_(aq) + CH₃COO^-_(aq)
   There is another common definition of an acid. It is the Lewis definition. A Lewis acid is an electron-pair acceptor.

   Acid
   Used as an adjective to describe sharp or sour flavours. Acidity is a vital component of wine: it helps red wines keep their colour and gives white wines their balance. Too much acidity, and a wine is tart and unpleasant; too little and the wine is 'flabby' and uninteresting. Grapes start out with high concentrations of organic acids which then disappear as the grapes ripen; consequently, in warm regions it is common practice to add acids to the unfermented grape juice to counter the lack of them in the grapes. In contrast, winemakers from wretchedly cool areas, such as parts of Germany and the UK, often have to deacidify.

    acid
    Acid is a type of compound that contains hydrogen and dissociates in water to produce positive hydrogen ions. The reaction, for an acid HA is commonly written: HA H+ + A- In fact, the hydrogen ion (the proton) is solvated, and the complete reaction is: HA + H2O H3O+ + A- This definition of acids comes from the Arrhenius theory. Such acids tend to...
