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.

∙ 12y agoChlorine 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 chemical symbol Cl?
Cl is the symbol for chlorine. Watch out when you write chemical symbols that you correctly use upper and lower case! The superscript minus sign tells you that the chlorine has gained an electron and become a chloride ion, negatively charged.
How many ml is 150 g of chlorine granules?
A measurement is the same in milliliters as in grams. One is equal to the other. 150 g of Chlorine Granules are equivalent to 150 ml of Chlorine Granules.
Is clorine reactive?
Chlorine is VERY reactive. Many of the compounds formed with chlorine are very dangerous. 2. I recall Asimov claiming that iron would burn (sic) in a chlorine atmosphere. After ignition of some sort I presume. I guess that, since iron(III) chloride is a real compound, that would be evidence that chlorine is reactive with iron. I know that FeCl3 will reacts exothermically in water, so that would sort of be "buring".
What does oxygen mixed with chlorine create?
It makes a mixture of oxygen and chlorine. There are many compounds between chlorine and oxygen, but they are not made by direct reaction of the elements.
What is breakpoint chlorination?
Break point chlorination refers to the continuous addition of chlorine to the water until the chlorine enquiry is met and all present ammonia is oxidized. Once the break point is reached, only free chlorine remains.
