Discovery and year

Chlorine (Cl) Chlorine in its pure form was discovered in 1774 by Carl Wilhelm Scheele, a chemist of German and Swedish descent. It was produced in a reaction of manganese (IV) oxide with hydrochloric acid.

Hydrogen (H) Hydrogen was discovered by Henry Cavendish in 1766 when, upon applying acid to some metals, he noticed that a previously unknown flammable gas was given off.

BIOGRAPHIES

Visual beings

Henry Cavendish (1731-1810): Henry Cavendish was a British scientist famous for discovering "hydrogen" in 1766, which he called "inflammable air", showing that when burned it produced water, which helped identify the composition of water as a combination of oxygen and hydrogen. He also carried out important research on electricity and the density of the Earth, known as the "Cavendish experiment", with which he calculated with great precision the gravitational constant.

Carl Wilhem Scheele (1742-1786): was a Swedish-German chemist known for his discoveries in the field of chemistry, especially for the discovery of "oxygen" in 1772, before Joseph Priestley, although Priestley published his findings first. In addition to this important discovery, Scheele also discovered several elements and compounds such as chlorine, manganese, glycerol and tartaric acid.

WHERE IS EACH ATOM?

Chlorine (Cl) Chlorine is the most abundant halogen in the marine ecosystem, with a concentration of 18,000 ppm, while in the Earth's crust it is found in lower proportion (130 ppm).

Hydrogen (H) Hydrogen is present in our bodies, in the air we breathe, in the water we drink, but also in plants and animals, in the stars and planets that make up the universe.

WHAT DOES IT CAUSE?

Hydrochloric acid can cause severe skin burns, irritation, and in the worst cases, disfigurement and death.

Due to its reactivity, it can corrode different materials, one of them being metal, since in metals the H ions react with the metal atoms, forming hydrogen gas and dissolving the metal.

It is essential to make the relevant checks. Not a single typo should be left!

hypochlorite

hypochlorous acid

chlorate

A great presentation:

'Your content is liked, but it engages much more when it is interactive'-Genially

It is used, for example, to clean, treat and galvanize metals, tan leather, and in the refining and manufacturing of a wide variety of products.

What do we use it for?

Sodium (Na) When it is mixed, they produce highly flammable hydrogen gas and can cause explosions.

Aluminum (Al)can quickly generate a cloud of hydrogen gas, which is very dangerous to health

Magnesium (Mg)Generates hydrogen gas, which is highly flammable and harmful to health
