What are the different concentrations of hydrogen peroxide?
hydrogen peroxide (H 2 o 2 ) varies from water (H 2 o) by the presence of another single oxygen atom. Because another oxygen atom is "electron loving" or electrophilic, hydrogen peroxide is a very powerful oxidation agent. The added oxygen also makes hydrogen peroxide quite unstable if it is not quite clean. Hydrogen peroxide is usually dissolved in water due to the risk of burns and instability induced by contamination associated with pure form and is used in suitable dilution for the task. There are a number of different concentrations of hydrogen peroxide with commercial meaning. It is also used for cleaning carpets, polishing metals and whitening of paper products. In addition, it is used in the laboratory in the sanitation pool and wastewater treatment. Included between different concentrations of hydrogen peroxide used are very high concentrations used for rocket fuel. In this respect, peroxide is used not only in space -designed missiles but also for devices such as rocket belts for “Vnithe Criminal Space ”that uses a 90%concentration.
hydrogen peroxide dissolved in water is a less safety problem. This is particularly important at high concentrations, at this point the decomposition of catalytic peroxide can lead to the formation of not only oxygen but dangerous vapors. A much lower concentration of hydrogen peroxide is required when used as a gargle, disinfectant or hair lightener. Such uses require the lowest of commercially different concentrations of hydrogen peroxide - 3%. Although this concentration is purchased, most dentists recommend 50:50 dilutation, reducing peroxide strength to approximately 1.5%.
slightly higher human peroxide concentrations can be available in some places-6% is easily available, for example, in the UK. In the laboratory, the most commonly observed from various concentrations of hydrogen peroxide is 30%. Another commercially available grade is 35%-tzv.“Food class”. Food and drug administration (FDA), US government agency, condemned the use of this product and recommends consumers who do not buy 35% hydrogen peroxide for human use. Stronger concentrations for use because fuel can run up to 98%.
different concentrations of hydrogen peroxide can be created in the same way. Previously, peroxide was produced by electrolysis of sulfuric acid or some other similar sulphate material. In 2011, the anthrachinone-process hydrogenation of catalytic oxidation-
