How did people discover oxygen?

Answer 1

Oxygen was discovered in 1772 by Carl Wilhelm Scheele, but he did not publish his discovery until after Joseph Priestly had published his independent discovery of oxygen in 1775. As a result, Priestly is usually credited with the discovery.

Answer 2

Oxygen was discovered by a Swedish pharmacist named Carl Wilhelm Scheele. He wrote about it in his book Treatise on Air and Fire in 1755, but the document was not published until 1777.

Joseph Henry (1797-1878), the physicist, is usually credited with the discovery because he published first, in 1775.

The name "oxygen" was invented by Antoine Lavoisier.

Answer 3

Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele. He had produced oxygen gas by heating mercuric oxide and various nitrates by about 1772. Scheele called the gas 'fire air' because it was the only known supporter of combustion.

In the meantime, an experiment was conducted by the British clergyman Joseph Priestley on August 1, 1774 focused sunlight on mercuric oxide (HgO) inside a glass tube, which liberated a gas he named 'dephlogisticated air' He noted that candles burned brighter in the gas and that a mouse was more active and lived longer while breathing it. After breathing the gas himself, he wrote: " Priestley published his findings in 1775 in a paper titled "An Account of Further Discoveries in Air" which was included in the second volume of his book titled Experiments and Observations on Different Kinds of Air. Because he published his findings first, Priestley is usually given priority in the discovery.

Answer 4

Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. He called the gas "fire air" because of the brilliant sparks it produced when it came in contact with hot charcoal dust. He repeated this experiment by heating potassium nitrate, Mercury oxide, and many other materials and produced the same gas. He collected the gas in pure form using a small bag. He explained the properties of "fire air" using the phlogiston theory, which was soon discredited by Lavoisier. He carefully recorded his experiments in his notes, but waited several years before publishing them.
