acid rain: Acid deposition - commonly called acid rain - is caused by emissions of sulphur dioxide and nitrogen oxides Although natural sources of sulphur oxides and nitrogen oxides do exist, more than 90% of the sulphur and 95% of the nitrogen emissions occurring in eastern North America are of human origin These primary air pollutants arise from the use of coal in the production of electricity, from base-metal smelting, and from fuel combustion in vehicles Once released into the atmosphere, they can be converted chemically into such secondary pollutants as nitric acid and sulfuric acid, both of which dissolve easily in water The resulting acidic water droplets can be carried long distances by prevailing winds, returning to Earth as acid rain, snow, or fog

acid rain: Acid rain is rain polluted by acid that has been released into the atmosphere from factories and other industrial processes. Acid rain is harmful to the environment. Acid precipitation falling as rain. rain that contains harmful acid which can damage the environment and is caused by chemicals in the air, for example from cars or factories. Any precipitation, including snow, that contains a heavy concentration of sulfuric and nitric acids. This form of pollution is a serious environmental problem in the large urban and industrial areas of North America, Europe, and Asia. Automobiles, certain industrial operations, and electric power plants that burn fossil fuels emit the gases sulfur dioxide and nitrogen oxide into the atmosphere, where they combine with water vapour in clouds to form sulfuric and nitric acids. The highly acidic precipitation from these clouds may contaminate lakes and streams, damaging fish and other aquatic species; damage vegetation, including agricultural crops and trees; and corrode the outsides of buildings and other structures (historic monuments are especially vulnerable). Though usually most severe around large urban and industrial areas, acid precipitation may also occur at great distances from the source of the pollutants

acid-base theory: Any of several theories that give rise to alternative definitions of acids and bases. The original theory was based on Svante Arrhenius's electrolytic theory of solutions and involved the dissociation of water into hydrogen and hydroxide ions. To explain the behaviour of a chemical, particularly if water is not present, two other theories were developed. The most widely accepted and useful is the Brønsted-Lowry definition (1923): An acid is a chemical that tends to lose a proton (H^+), and a base is a chemical that tends to gain a proton. Another is the Lewis definition (also 1923): An acid (see electrophile) is a chemical that can accept an electron pair from a base (see nucleophile), which they share to form a covalent bond. The three theories have superficial similarities but subtle and important differences for certain applications

It is the chief acid of vinegar. the acid in vinegar (acétique, from acetum ). Most important carboxylic acid (CH3COOH). Pure ("glacial") acetic acid is a clear, syrupy, corrosive liquid that mixes readily with water. Vinegar is its dilute solution, from fermentation and oxidation (see oxidation-reduction) of natural products. Its salts and esters are acetates. It occurs naturally as a metabolic intermediate in body fluids and plant juices. Industrial production is either synthetic, from acetylene, or biological, from ethanol. Industrial chemicals made from it are used in printing and as plastics, photographic films, textiles, and solvents
