The Greek word chlōrós derived in French chlore, which reached our idiom What chlorine. This is the name of the chemical element whose symbol is Cl and its atomic number is 17.
Chlorine, which in the periodic table of the elements is part of the set of the halogens, normally appears as a yellowish or greenish gas characterized by its toxicity. It is an element present in copious amounts in our planet.
Plant tissues and animals, salt deposits and sea water have chlorine. It is important to note that, in nature, it is not usually found in its pure state due to its tendency to react quickly when in contact with various chemical compounds and elements. That is why it appears as chlorates, chlorites or chlorides.
Carl Wilhelm Scheele, a Swedish chemist born in 1742 and died in 1786, was the one who discovered chlorine in 1774. Scheele, however, he thought that chlorine was a compound with oxygen. It was not until 1810 that another chemist, the English Humphry Davy (1778-1829), managed to show that chlorine was a chemical element.
Chlorine, through various compounds, has multiple uses. One of the most frequent is disinfection of the Water. Chlorine is often added to the water used to fill swimming pools, for example. This substance is also used as a pesticide and in the manufacture of plastics, solvents, bleaches and dyes. Below we delve into these and other uses in more detail.
In addition to swimming pool water, drinking water can also be kept safe thanks to the chemistry of chlorine. Before governments began treating water with disinfectants based on this element, hundreds of people died each year from diseases such as typhoid fever, hepatitis A, dysentery and cholera, among others that are transmitted through the Water.
The action of chlorine in these cases, specifically when used in disinfectants for swimming pool water, focuses on destroying the pathogens capable of causing diseases, both those mentioned in the previous paragraph as well as skin rashes, diarrhea and athlete’s foot.
Chlorine is also used in the home, in this case in the form of a product that is used to disinfect and whiten clothing and bathroom and kitchen furniture. We talk about the diluted bleach and some solutions in water, which act effectively against germs present in various parts of the house that can cause diseases, among which is the norovirus.
In another area, chlorine serves to protect plantations from pests, to guarantee the quality and abundance of crops, which then become human food. Thanks to its use it is possible to destroy salmonella and virus from E. coli, to cite just two examples.
Chlorine is also used to make many of the most widely used medications today, including those used to ease the symptoms of certain allergies, reduce arthritis pain, and lower cholesterol. On articles typical of clinical medicine you can also find chlorine; some examples are stitches, inhalers, and blood bags.
Constantius Chlorine, finally, is the Name with which it is known Flavio Valerio Constancio, Roman emperor who held the titles of Caesar and Augustus. He founded the Constantinian dynasty and helped defeat the usurper Alecto, as well as having led various military campaigns. His death was sudden and triggered the collapse of the government system established by the Emperor Diocletian.
