The Curse of Phlogiston

The video explores the historical development of the Flogiston theory, proposed by Johann Becker in 1667, which misled chemists for over a century. It highlights Henry Cavendish's experiments with zinc and acid, leading to the isolation of hydrogen, though he misidentified it as Flogiston. Joseph Priestley's work with mercury oxide led to the isolation of oxygen, but due to the prevailing Flogiston theory, its significance was not recognized. The video underscores how the Flogiston theory hindered the understanding of chemical elements.
