e. An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO 2 OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak.
Citric acid is an organic compound with the skeletal formula H O C(CO 2 H)(CH 2 CO 2 H) 2. [10] It is a colorless weak organic acid. [10] It occurs naturally in citrus fruits.In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.
Kawah Putih is a sizeable highly acid lake (pH 0.5-1.3) that changes colour from bluish to whitish green, or brown, depending on the concentration of sulfur and the temperature or the oxidation state. [ 4 ] The sand and rocks surrounding the lake have been also leached into whitish colours through interaction with the acidic lake waters (with ...
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H2SO4. It is a colorless, odorless, and viscous liquid that is miscible with water.
The broadest definition of natural product is anything that is produced by life, [4][13] and includes the likes of biotic materials (e.g. wood, silk), bio-based materials (e.g. bioplastics, cornstarch), bodily fluids (e.g. milk, plant exudates), and other natural materials (e.g. soil, coal). Natural products may be classified according to their ...
Vinegar. A variety of flavored vinegars, for culinary use, on sale in France. Vinegar (from Old French vyn egre 'sour wine ') is an aqueous solution of acetic acid and trace compounds that may include flavorings. Vinegar typically contains from 5% to 18% acetic acid by volume. [1] Usually, the acetic acid is produced by a double fermentation ...
Acetic acid is the second simplest carboxylic acid (after formic acid). It is an important chemical reagent and industrial chemical across various fields, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood glue, and synthetic fibres and fabrics.
Terephthalic acid is an organic compound with formula C 6 H 4 (CO 2 H) 2. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tons are produced annually. [8]
