What is ch3co2h




















It is classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can attack the skin. Acetic acid is the second simplest carboxylic acid after formic acid. It consists of a methyl group attached to a carboxyl group. It is an important chemical reagent and industrial chemical, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibres and fabrics.

In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is controlled by the food additive code E as an acidity regulator and as a condiment.

In biochemistry, the acetyl group, derived from acetic acid, is fundamental to all forms of life. Read full article at Wikipedia. Average Mass. Monoisotopic Mass. Metabolite of Species. Daphnia magna NCBI:txid See: PubMed. Roles Classification. Chemical Role s :. Bronsted acid A molecular entity capable of donating a hydron to an acceptor Br o nsted base.

Biological Role s :. The IUPAC name for the chemical is ethanoic acid, a name formed using the convention of dropping the final "e" in the alkane name of the longest carbon chain in the acid ethane and adding the "-oic acid" ending. Even though the formal name is ethanoic acid , most people refer to the chemical as acetic acid.

In fact, the usual abbreviation for the reagent is AcOH, partly to avoid confusion with EtOH, a common abbreviation for ethanol. The common name "acetic acid" comes from the Latin word acetum , which means vinegar. Acetic acid has an acidic character because the hydrogen center in the carboxyl group -COOH separates via ionization to release a proton:.

This makes acetic acid a monoprotic acid with a pKa value of 4. At a concentration comparable to that in vinegar 1. However, in very dilute solutions, over 90 percent of the acid dissociates. Acetic acid is a versatile acidic solvent. As a solvent, acetic acid is a hydrophilic protic solvent, much like water or ethanol.

Acetic acid dissolves both polar and nonpolar compounds and is miscible in both polar water and nonpolar hexane, chloroform solvents. However, acetic acid is not fully miscible with higher alkanes, such as octane. Acetic acid ionizes to form acetate at physiological pH. The acetyl group is essential to all life.

Acetic acid bacteria e. Fruits produce acetic acid as they ripen. In humans and other primates, acetic acid is a component of vaginal lubrication, where it acts as an antibacterial agent. When the acetyl group binds to coenzyme A, the holoenzyme is used in the metabolism of fats and carbohydrates.

Acetic acid, even at 1 percent concentration, is an effective antiseptic, used to kill Enterococci , Streptococci , Staphylococci , and Pseudomonas. Dilute acetic acid may be used to control skin infections of antibiotic bacteria, particularly Pseudomonas.

The injection of acetic acid into tumors has been a cancer treatment since the early 19th century. Barclay, J. Gupta, Chhavi, et al. Roger, Elizabeth, and Oguchi Nwosu.
