What is Vinegar?
Vinegar may be defined as a condiment made from various sugary and starchy materials by alcoholic fermentation and subsequent acetic fermentation. Vinegar is also known as acetic acid. The term “vinegar” has been derived from the french word “VinAgre” which refers to sour wine. Vinegar is actually an aqueous solution of acetic acid and some other substances. Acetic acid is produced by a double fermentation process in which sugar is converted first into ethanol and then the ethanol is oxidized to form acetic acid. Vinegar is used mainly for cooking purposes like in pickling, as an ingredient, etc. It can also be used as a cleaner. The boiling point of acetic acid is 118.10 C and the melting point of acetic acid is 16.60 C .
Chemical Formula of Vinegar
Acetic acid is composed of the atoms of carbon, hydrogen, and oxygen elements. The density of the acetic acid is 0.96 grams per ml. Acetic acid involves a carboxylic acid functional group. The carboxylic acid group is represented by -COOH. Acetic acid consists of two carbon atoms, two oxygen atoms, and four hydrogen atoms. Hence, “C2H4O2” represents the chemical formula of acetic acid.
Structural Formula of Vinegar
Vinegar is composed of two carbon atoms in which one carbon atom is attached to an oxygen atom by a double bond, the hydroxyl group by a single bond, and to the next carbon atom by a single bond. Then the next carbon is bonded to three hydrogen atoms by a single bond. So, the structural formula of acetic acid is “ CH3COOH”. The molecular mass of acetic acid is 60.0 grams per mole.
