Henry Cavendish, Russian chemist Dmitry Mendeliv once described hydrogen as the most striking element in the periodic table elements. Characteristic sayings mean the lower level elements of the periodic table. Preparing hydrogen is very easy. It can be prepared by pouring sulfuric acid on the granules in the general laboratory. So it is not about a delay to discover it. While chemistry was not established as a science, it was known to all the components of the preparation. For example, people knew about hydrochloric, sulfuric and nitric acid, and iron and zinc. Chemists also studied them. But there was an opportunity for hydrogen to be produced in exactly the same way.

Among those who noticed this, Russian scientist Mikhail Vasilyevich Lomonosov was one of the few. In 1745, “In relation to the light of metal,” he mentioned that “the special metals like an iron dissolve in acidic alcohol, the burning flame emerges from the mouth of the flask.” Acid was meant to refer to acidic alcohol in the term. Lomonosov hydrogen was observed, but after following the belief he called it a flogiston. When the metal is dissolved in acids, the steam excretion emits, which is more likely to be a phlogiston and it is a phlogiston theory. Flogistan theory was also well-liked. When a chemists began to observe this combustible air, they could not be called specific, but a paper published in 1766 could be considered as a normal starting point.

The article, published by J Black, was named “experiments with artificial winds”. At this time, English scientist Henry Cavendish began a detailed study of closed gas. Binding means being confined to various compounds, they can be freed from the compounds through reaction. Cavendish knew the matter of combustible air, and he started research from there. Iron, By combining hydrochloric or sulfuric acid with zinc and tin, it produces combustible air at different times and recognizes the characteristics of all. But he also called these gases as frogastons and he explained the nature of the substance produced by the follower. J Black’s torch wind and Cavendish closed winds, all were already known. But they were able to stand a summary which is an integral part of chemistry science.

The combustible air and the closed air were separated from the normal air and from each other. The combustible wind was incredibly light. And the Cavendish was the mass of closed air discovered. It was said by cavendish fluorphine, but the flogistone could not have any positive mass. Here he is in conflict with his previous research. The Cavendish first drew the first general air density ‘1’ and found out the dense wind and closed air density, whose value was 0.09 and 1.57 respectively. After losing the burn, the metals lose some mass. In that case, it can not be a phlogiston. To solve these opposing theories, the Cavendish said, the inflammable air was produced through the intervention of the fluogiston and water. In essence, when the formation of his torch wind was finally produced, hydrogen was finally produced. The Cavendish essentially combined the combustible wind with closed winds. This is the story of 1766.
