Vinegar test dry ice. Vinegar highlights tumors, which have more DNA, and therefore less water and more protein, than healthy tissue. As of 2011, Thailand has adopted the technique in twenty-nine of its (then) seventy-five provinces, and 500,000 women have been tested at least once. The vinegar test does have important limitations and disadvantages for cervical cancer screening, as well; please refer to that section in the main Cervical_screening article. 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
Orthocarbonic acid to be observed. However, theoretical studies suggest that NaCO might be stable. The tetravalent moiety CO is found in stable organic compounds; they are formally esters of orthocarbonic acid, and therefore are called orthocarbonates. For example, Tetraethoxymethane can be prepared by the reaction between chloropicrin and sodium ethoxide in ethanol. Polyorthocarbonates are stable polymers that might have applications in absorbing organic solvents in waste treatment processes, or in dental restorative materials. The explosive trinitroethylorthocarbonate possesses a orthocarbonate core. Orthocarbonic acid Orthocarbonic acid (methanetetrol) is the name given to a hypothetical compound with the chemical formula HCO or C(OH). Its molecular
