Vinegar test Vinegar test Vinegar test is a cervical cancer testing method that uses acetic acid, a major component of vinegar. It has been found to be useful as an effective and inexpensive screening test. It has the potential, say researchers from the University of Zimbabwe and Johns Hopkins University, to improve the chances of preventing cancer in developing world. The technique, termed VIA (Visual Inspection with Acetic Acid)/Cryo, was endorsed by the World Health Organization in 2010. Vinegar is brushed on a woman’s cervix and precancerous spots turn white. These can be instantly frozen off with a metallic probe cooled with
Cyanuric acid Cyanuric acid Cyanuric acid or 1,3,5-triazine-2,4,6-triol is a chemical compound with the formula (CNOH). Like many industrially useful chemicals, this triazine has many synonyms. This white, odorless solid finds use as a precursor or a component of bleaches, disinfectants, and herbicides. In 1997, worldwide production was 160 million kilograms. Cyanuric acid is the cyclic trimer of the elusive species cyanic acid, HOCN. The two structures shown in the infobox are tautomers that readily interconvert. However, mixture with melamine forms melamine cyanurate, which locks cyanuric acid in the tri-keto tautomer and makes melamine cyanurate insoluble in water. The triol tautomer, which
