Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the skin, and silver nitrate produces noticeable black stains. Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion.
Chlorobenzene (abbreviated PhCl) is an aryl chloride and the simplest of the chlorobenzenes, consisting of a benzene ring substituted with one chlorine atom. Its chemical formula is C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals.

Piranha solution should always be prepared by adding hydrogen peroxide to sulfuric acid slowly, never in reverse order. [5] [6] This minimises the concentration of hydrogen peroxide during the mixing process, helping to reduce instantaneous heat generation and explosion risk. Mixing the solution is an extremely exothermic process.
DDQ and an acid catalyst has been used to synthesise a steroid with a phenanthrene core by oxidation accompanied by a double methyl migration. [9] In the process, DDQ is itself reduced into an aromatic hydroquinone product. Sulfur and selenium are traditionally used in aromatization, the leaving group being hydrogen sulfide. [10]
Skin exposure to the solvent mixture may cause irritation and defatting injury. Brake cleaners decompose rubber and some types of plastics by removing binding components. The rubber appears unchanged at first; however, it will become brittle, and after a few weeks to months cracks and fractures appear.
