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 ...
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]
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 .
The hypochlorites in liquid bleach and bleaching powder can react with ammonia to form a number of products, including monochloramine (NH 2 Cl), then dichloramine (NHCl 2) and finally nitrogen trichloride (NCl 3). Similar reactions may occur with amines or related compounds and biological materials (such as urine). The result depends on the ...
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
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.
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 ...
This problem is avoided by the use of sodium hypochlorite, which is a relatively inexpensive solution used in household bleach that releases free chlorine when dissolved in water. Chlorine solutions can be generated on site by electrolyzing common salt solutions. A solid form, calcium hypochlorite, releases chlorine on contact with water ...
