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 ...
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 .
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]
The process of electrochlorination is a simple application based on the chloralkali process (in an unpartitioned cell). It is the electrolysis of saltwater to produce a chlorinated solution. The first step is removing any solids from the saltwater. Next, the saltwater streams through an electrolyzer cell's channel of decreasing thickness.
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 ...
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.
Properties of isolated, closed, and open thermodynamic systems in exchanging energy and matter. A thermodynamic system is a body of matter and/or radiation separate from its surroundings that can be studied using the laws of thermodynamics. Thermodynamic systems can be passive and active according to internal processes.
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 ...
