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
Chemical compound for the chemical elements, and subscripts to indicate the number of atoms involved. For example, water is composed of two hydrogen atoms bonded to one oxygen atom: the chemical formula is HO. In the case of non-stoichiometric compounds, the proportions may be reproducible with regard to their preparation, and give fixed proportions of their component elements, but proportions that are not integral [e.g., for palladium hydride, PdH (0.02 < x < 0.58)]. Chemical compounds have a unique and defined chemical structure held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by
