He put her body in the bin and poured 20 liters of Hydroch WebPiranha solution keeps true to its name; the mixture of sulfuric acid and hydrogen peroxide is a powerful oxidant that eats almost anything, even elemental carbon. Always limit the amount of Piranha solution. It is formed by mixing hydrogen fluoride (HF) and antimony pentafluoride (SbF 5 ). Store waste solution in a container equipped with a vented cap available from EHS. "Piranha solution" (concentrated hydrogen peroxide in concentrated sulfuric acid) eats organics, oh yes indeed, and can explode while doing it; while making it, too.

It's made of sulfric acid and hydrogen peroxide. Sulfuric acid reacts violently with alcohol and water to release heat. Do not mix piranha solution with incompatible materials such as organic acids, organic solvents, or other organic materials. Do not mix with bases (e.g., Photoresist). Mixing piranha with incompatible materials can lead to an explosion. These cleaning methods include washing and refluxing in piranha solution (sulphuric acid and hydrogen peroxide combine with the formation of peroxymonosulfuric acid) and other solutions, along with ultraviolet light and ozonolysis [ [35], [36], [37] ]. 609-258-6271, Environmental Health and Safety Sulfuric acid In case of inhalation: Conscious persons should be assisted to fresh air.
