Scheele och syrets gåta I slutet av 1700-talet försökte flera europeiska kemister analysera luftens beståndsdelar. Bland dessa vetenskapsmän fanns en svensk apotekare som saknade universitetsutbildning – Carl Wilhelm Scheele. Hans upptäckt av »eldsluft« skulle visa sig vara avgörande.

Discovery of Oxygen by Carl Wilhelm Scheele is a short but profound book on experiments that led to the discovery of oxygen. This is quite an old book and talks about the time when even conducting these experiments was a difficult task. Overall, a good one time read. Carl Wilhelm Scheele was furthermore the first to discover the adsorption of gases by charcoal. His most important achievement, however, was the discovery of oxygen in the air, which Carl Wilhelm Scheele described in his main work "Chemical Observations and Experiments on Air and Fire" (Uppsala and Leipzig, M. Swederus 1777). Oxygen was discovered by two different people on two separate occasions in the same year of 1774. The men who discovered it were Joseph Priestly and Carl Wilhelm Scheele.

Carl Wilhelm Scheele (1742-1786) has an important place in the history of the discovery of respiratory gases because he was undoubtedly the first person to prepare oxygen and describe some of its properties.

His fellow chemist and good friend, Torbern Bergman (1735-1784), was one of the pioneers in analytical and 6 Dec 2017 He called the element “fire air” because he believed, based on the theories of his time, that a substance that made up fire was released from items  In 1772, some two years before Priestley, he isolated oxygen, the key to the new chemistry.

Oxygen was officially discovered in 1774, but had been discovered by several chemists without realizing it was a distinct element. Joseph Priestly is usually given credit for the discovery of oxygen, however it has been said that Carl Wilhelm Scheele had also independently discovered the element. Both chemists were able to produce oxygen by heating mercuric oxide (HgO).

Carl Wilhelm Scheele (1742-1786) On December 19, 1742 (Gregorian Calendar), Swedish Pomeranian pharmaceutical chemist Carl Wilhelm Scheele was born. Scheele is best known for his discovery of oxygen and other chemical elements.

In the meantime Priestley had published his discovery of oxygen gas, and other observations in Scheele's book had been made public, as well, much to Scheele's displeasure.
