Carl Wilhelm Scheele created chlorine in 1774 mistakenly thought it contained oxygen. Then Hmphry Davy named it.
Chlorine's mass number is 35.5. This is an average value due to the presence of two isotopes of chlorine, chlorine-35 and chlorine-37, in nature.
Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.
Total Chlorine = Free Chlorine + Combined Chlorineor, put another wayTotal Chlorine - Free Chlorine = Combined ChlorineFree Chlorine is the chlorine that is doing its job.Combined Chlorine is the chlorine that has combined with contaminants such as nitrogen. It is ineffective as a sanitizer and it is noxious.Total Chlorine is the total of these two levels.To eliminate the Combined Chlorine (making all the chlorine in the pool Free Chlorine) you must shock the pool to remove the contaminants. You must reach "Breakpoint Chlorination", which is the addition of chlorine to your pool equivalent to the Combined Chlorine level times 10.example:Total Chlorine = 1.5ppmFree Chlorine = 1.0ppmSo, the Combined Chlorine (the difference between the two tests) is .5ppmBreakpoint chlorination, in this example would be .5ppm X 10 = 5ppm. So, in this example, you would add enough chlorine to your pool to raise the chlorine level up by 5 parts per million.
ClF5 Is the formula for Chlorine pentaflouride.

Salt -sodium chloride
This compound is magnesium chloride (MgCl2).
When sodium and chlorine are combined, they form sodium chloride, which is commonly known as table salt. This compound is formed by the transfer of one electron from sodium to chlorine, resulting in the formation of a stable ionic bond.
Chlorofluorocarbons (CFCs) break down in the stratosphere under ultraviolet light to form chlorine atoms. These chlorine atoms can then react with ozone molecules, leading to the depletion of the ozone layer.
The element with an atomic mass of 35.453 is chlorine. It is a halogen and has the atomic number 17.
Chlorine is produced by the process called electrolysis of salt water. Reaction in the presence of electricity: 2NaCl + 2H20 _> Cl2 (chlorine gas) + 2NaOH + H2 Cl2 is released in its gaseous form which is used to create chlorine compounds for sanitizing and bleaching.
Chlorine has a lot of different isotopes but the 2 stable ones are chlorine 35 and chlorine 37
Chlorine (Cl) atoms make up the element chlorine.
Chlorine
Chlorine dioxide is a different chemical compound from chlorine. While they both contain the element chlorine, there is no chlorine in the form of Cl2 in chlorine dioxide. Chlorine dioxide (ClO2) is a strong oxidizing agent used for water treatment and disinfection.
Cl2 is chlorine. Chlorine exists as a diatomic molecule.
Chlorine's mass number is 35.5. This is an average value due to the presence of two isotopes of chlorine, chlorine-35 and chlorine-37, in nature.
