About this deal
Early attempts failed to produce neat hydrogen peroxide. Anhydrous hydrogen peroxide was first obtained by vacuum distillation. [24] Fill a large bowl or clean sink with water and add one-fourth cup of peroxide. Wash produce in the water and peroxide mixture, rinse thoroughly with clean water and dry. Bonus: Cleaning your produce with peroxide could extend its shelf life. The amount of hydrogen peroxide in biological systems can be assayed using a fluorometric assay. [18] Discovery [ edit ]
Under alkaline conditions, hydrogen peroxide is a reductant. When H 2O 2 acts as a reducing agent, oxygen gas is also produced. For example, hydrogen peroxide will reduce sodium hypochlorite and potassium permanganate, which is a convenient method for preparing oxygen in the laboratory:NH 4] 2S 2O 4 was itself obtained by the electrolysis of a solution of ammonium bisulfate ( [NH 4]HSO 4) in sulfuric acid. [32] Other routes [ edit ]
The rate of decomposition increases with rise in temperature, concentration, and pH. H 2O 2 is unstable under alkaline conditions. Decomposition is catalysed by various redox-active ions or compounds, including most transition metals and their compounds (e.g. manganese dioxide ( MnO 2), silver, and platinum). [38] Oxidation reactions [ edit ] Looking for a cheap and effective way to remove germs and pesticides from fruits and vegetables? Peroxide can do the job. The redox properties of hydrogen peroxide depend on pH. In acidic solutions, H 2O 2 is a powerful oxidizer. When you use peroxide, go for medical-grade peroxide, which is 3% strength. That means it’s 97% water and 3% peroxide. “Medical grade is strong enough for household use,” says Dr. Beers.
