Now, solve this instance: The presence of this compound in drinking water can be detected using a colorimetric procedure described by Snell and Snell, or through reactions with potassium permanganate, potassium iodide, or ceric sulfate. Sato et al proposed an alternative to traditional adipic acid production using a 30 percent solution of this molecule. This compound may be used to separate titanium from iron, and the second step of the (*) Ruff degradation method uses this compound and an iron salt. Commercial production of this compound typically uses stabilizers such as acetophenetidin and acetanilide, and this molecule is used along with a Lewis acid to produce esters from ketones in the Baeyer-Villiger Oxidation. Along with MCPBA, it is often used to create epoxides. In the body, it is broken down by catalase, and generated by superoxide dismutase. For 10 points, name this potent oxidative species often used as a disinfectant, with chemical formula H2O2.
