Chlorine is chlorine, so the chlorine in bleach is the same as the chlorine in drinking water and in a swimming pool. In fact, you can use chlorine bleach to treat a swimming pool or to treat drinking water. A gallon of bleach provides 1 part per million (PPM) of chlorine to 60,000 gallons (about 250,000 liters) of water.
For example, sodium dithionite is a powerful reducing agent that can be used as a bleach.at can be used as a bleach. How Bleach Chemicals Work An oxidizing bleach works by breaking the chemical bonds of a chromophore (part of a molecule that has color).
You may have also noticed that fabrics left out in the sun will look faded or bleached over time. Does sunlight have bleach in it? Nope! But sunlight can work like bleach. High energy ultraviolet sunlight can disrupt the chemical bonds in chromophores, causing them to lose their color much like the oxidation process with bleach.
Since chlorine bleach was faster and more effective than the bleaches people had been using, it quickly became the most popular household bleach. Today, when we say "bleach," we usually mean chlorine bleach. So what exactly is chlorine bleach, and how does it work?
Work with bleach in a well ventilated area. If you are using it in a bathroom, turn on the fan or open a window. If you get chlorine bleach on your skin, wash it off immediately using plenty of water.
The discovery of chemical bleaches was based on the work of three scientists in the eighteenth and nineteenth centuries. A Swedish scientist named Carl Wilhelm Scheele discovered chlorine. (This is significant because sodium hypochlorite contains chlorine.) A French scientist named Claude Berthollet discovered that chlorine could bleach fabrics.
Chlorine is commonly used to kill bacteria in water. It is widely used to purify swimming pool, spa and drinking water. When it is dissolved in sodium hydrate it can be made into chlorine bleach or disinfectant. Disinfectant is used to kill germs, and chlorine bleach is used to whiten clothes and to disinfect.
Chlorine bleach contains the active ingredient sodium hypochlorite (NaOCl), while non-chlorine bleaches have different active ingredients for different purposes. Hydrogen peroxide, for instance, is common in color-safe bleaches, and sodium percarbonate or sodium perboate are typically used in "oxygen power" stain removers.
Chemical bleaches work in one of two ways: An oxidizing bleach works by breaking the chemical bonds that make up the chromophore. This changes the molecule into a different substance that either does not contain a chromophore, or contains a chromophore that does not absorb visible light.
Chlorine is the chemical most often used to keep swimming pools and Jacuzzis free of bacteria that can be hazardous to humans. While the bacteria-killing properties of chlorine are very useful, chlorine also has some side effects that can be annoying to humans, and possibly even hazardous. Chlorine ...
