the year 1774
Chlorine was observed for the first time by Jan Baptist van Helmont near 1630 (in Holland) and prepared for the first time in laboratory by Carl Wilhelm Scheele in 1774 (in Sweden), but considered it to be a compound of oxygen.
Sir Humphry Davy (in England) named it after identifying chlorine as a chemical element in 1810.

What is free chlorine in a pool?
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.
Is chlorine explosive?
Is chlorine explosive?Chlorine alone is not explosive.
What is chlorine an example of?
chlorine
How do you get high free chlorine to match total 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.

Why was chlorine gas invented?
It was not invented. Chlorine is a natural chemical element like oxygen or nitrogen.
How was the chlorine invented?
It was invented bythe action of Maganese Dioxide on Hydrochloric Acid.
Who invented isotopes?
Isotopes were not invented - they exist in nature. They were discovered when the atomic mass of Chlorine was measured at 35.5
What would happen if chlorine was not invented?
We would not have a nice pool to Swim in
What was invented in WWI?
Chlorine gas, machine guns, tanks, and planes were used for war.
Who invented chlorine in World War 1?
i think Borne Haber aGerman scientist.
What country invented the tank zeppelins and chlorine poison gas?
tank, UKzeppelin, Germanychlorine, Germany
In what war was chlorine gas first used as a weapon?
Invented by French chemist Claude Berthollet, chlorine gas was first used as a weapon by the military during the first World War in 1914. Chlorine gas was first used as a disarming weapon, and later as a fatal poison.
What element's atomic mass is 35.453?
Chlorine has an atomic mass of 35.453.
Chlorine was discovered in?
Chlorine gas was first observed by a Belgian chemist, Jan Baptist van Helmont, in about the year 1630, but the Swedish chemist Carl Wilhelm Scheele is credited with isolating Chlorine as an element in 1774, although he didn't recognize it as an element. That realization came in the early 1800's. Chlorine gas was first used as a weapon on April 22, 1915, at the Battle of Ypres. For more information, look up "Chlorine" on Wikipedia.
What atoms are in chlorine?
Chlorine is an elemental gas. The only atoms in chlorine are CHLORINE. A molecule of chlorine contains two atoms of chlorine (Cl2 ; Cl - Cl) Chlorine is found in the Periodic Table.
Atomic mass is 35.453?
Chlorine is a non metal element. Chlorine atomic mass is 35.453.
