Elephant's toothpaste. Elephant toothpaste reaction. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide ( H2O2) using potassium iodide (KI) or yeast and warm water as a catalyst. [ 1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. [ 2][ 3][ 4]
The peroxide value is defined as the amount of peroxide oxygen per 1 kilogram of fat or oil. Traditionally this was expressed in units of milliequivalents, although in SI units the appropriate option would be in millimoles per kilogram (N.B. 1 milliequivalents = 0.5 millimole; because 1 mEq of O2 =1 mmol/2=0.5 mmol of O2, where 2 is valence).
Oxidation state. In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom if all of its bonds to other atoms were fully ionic. It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound. Conceptually, the oxidation state may be positive, negative or zero.
A peroxisome(IPA:[pɛɜˈɹɒksɪˌsoʊm]) [1]is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryoticcells. [2][3]Peroxisomes are oxidative organelles. Frequently, molecular oxygen serves as a co-substrate, from which hydrogen peroxide(H2O2) is then formed.
Catalytic oxidation are processes that rely on catalysts to introduce oxygen into organic and inorganic compounds. Many applications, including the focus of this article, involve oxidation by oxygen. Such processes are conducted on a large scale for the remediation of pollutants, production of valuable chemicals, and the production of energy. [1]
Peroxidase. Peroxidases or peroxide reductases ( EC number 1.11.1.x) are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides, and should not be confused with other enzymes that produce peroxide, which are often oxidases .
Ethylenediaminetetraacetic acid ( EDTA ), also called EDTA acid after its own abbreviation, is an aminopolycarboxylic acid with the formula [CH 2 N (CH 2 CO 2 H) 2] 2. This white, water-insoluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+ ), forming water-soluble complexes even at neutral pH.
Hydrogen peroxide is an anti-fungal and anti bacterial solution that eliminates mold on a wide variety of surfaces. Just spray the undiluted solution directly onto the mold and let it sit for 10 ...
