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.

Chlorine was first isolated and identified as a chemical element by Swedish chemist Carl Wilhelm Scheele in 1774. However, it was British chemist Sir Humphry Davy who first produced chlorine gas in a laboratory in 1810.

What is chlorines mass number?
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.
What is free chlorine in a pool?
Free chlorine in a pool refers to the amount of chlorine available in the water to kill bacteria and algae. It is essential for maintaining water quality and preventing the growth of harmful microorganisms. Monitoring and adjusting free chlorine levels regularly is necessary to ensure the pool is safe for swimmers.
What do you do when your total chlorine is high and your free chlorine is low?
When total chlorine is high and free chlorine is low, it usually indicates that there is combined chlorine present in the water. This can be due to organic contaminants or inadequate sanitation. To address this issue, shock the pool with a higher dose of chlorine to break down the combined chlorine, and then test and adjust the levels accordingly. Additionally, ensure proper filtration, cleaning, and maintenance practices to prevent the buildup of combined chlorine.
What is the name of the covalent compound ClF3?
The covalent compound ClF3 is called chlorine trifluoride.
How do you get high free chlorine to match total chlorine?
To match high free chlorine with total chlorine, you can either dilute the water with chlorine-free water or add a dechlorinating agent to reduce the total chlorine level. It's important to maintain the proper balance to ensure safe swimming conditions while minimizing chlorine levels. Consulting a pool professional for specific guidance is recommended in this situation.
Why was chlorine gas invented?
Chlorine gas was not invented; it occurs naturally in small amounts. However, it gained notoriety during World War I when it was weaponized for chemical warfare due to its toxic properties and ability to cause respiratory distress and death in high concentrations.
How was the chlorine invented?
Chlorine was discovered in 1774 by Carl Wilhelm Scheele, a Swedish chemist. He produced the element by reacting hydrochloric acid with manganese dioxide. Later, in 1810, Sir Humphry Davy named the element "chlorine."
What was invented in WWI?
Chlorine gas, machine guns, tanks, and planes were used for war.
What would happen if chlorine was not invented?
If chlorine was not invented, water would not be able to be effectively disinfected, leading to increased levels of waterborne diseases and illness. Additionally, the use of chlorine as a bleaching agent in the production of paper, textiles, and other products would have to be replaced with alternative chemicals or processes.
What country invented the tank zeppelins and chlorine poison gas?

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.
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 element's atomic mass is 35.453?
The element with an atomic mass of 35.453 is chlorine. It is a halogen and has the atomic number 17.
How many chlorine has isotopes?
Chlorine has two stable isotopes: chlorine-35 and chlorine-37.
What atoms are in chlorine?
Chlorine consists of only chlorine atoms. In its elemental form, chlorine is diatomic, meaning it exists as a molecule consisting of two chlorine atoms bonded together (Cl2).
What halogen is in table salt?
Chlorine
Is there chlorine in chlorine dioxide?
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.
