What did Priestley do for oxygen?
Priestley was one of the first scientists who discovered oxygen. In 1774, he prepared oxygen by heating mercury oxide with a burning glass. He found that oxygen did not dissolve in water and it made combustion stronger. Priestley was a firm believer of phlogiston theory.
Why is there a dispute as to whether Priestley and Lavoisier discovered oxygen?
He said that Scheele doesn’t deserve for it because the publishment was late, so it is the choice between Priestley and Lavoisier. Priestley didn’t get the pure sample of oxygen, and he recognized the gas as the air without phlogiston. Lavoisier also recognized oxygen as the whole air or the cause of acidity.
