Sunlight acts as a bleach through a process leading to similar results: high-energy photons of light, often in the violet or ultraviolet range, can disrupt the bonds in the chromophore, rendering the resulting substance colorless. Extended exposure often leads to massive discoloration usually reducing the colors to a white and typically very ...
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
Liquid bleach, often called just bleach, is a common chemical household product that consists of a dilute solution of sodium hypochlorite (NaClO) and other secondary ingredients. It is a chlorine releasing bleaching agent widely used to whiten clothes and remove stains, as a disinfectant to kill germs , and for several other uses.
The use of chlorine dioxide minimizes the amount of organochlorine compounds produced. [20] Chlorine dioxide (ECF technology) currently is the most important bleaching method worldwide. About 95% of all bleached kraft pulp is made using chlorine dioxide in ECF bleaching sequences. [21] Chlorine dioxide has been used to bleach flour. [22]
For example, when household bleach and wastewater were mixed, 1–2% of the available chlorine was observed to form organic compounds. [44] As of 1994, not all the byproducts had been identified, but identified compounds include chloroform and carbon tetrachloride .
Chemical energy is the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, [1] food, and gasoline (as well as oxygen gas, which is of high chemical energy due to its relatively weak double bond [2] and indispensable for chemical-energy release in ...
Here’s why bleach is in short supply, and what experts say you can use instead. Why Is Bleach in Short Supply? The short answer is COVID-19.
In chemistry, hypochlorite, or chloroxide is an anion with the chemical formula ClO −.It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). [1]
