Phlogiston theory – Wikipedia

The phlogiston theory is a superseded scientific theory that postulated the existence of a fire-like element called phlogiston contained within combustible bodies and released during combustion. The name comes from the Ancient Greek φλογιστόν phlogistón, from φλόξ phlóx. The idea was first proposed in 1667 by Johann Joachim Becher and later put together more formally by Georg Ernst Stahl. Phlogiston theory attempted to explain chemical processes such as combustion and rusting …

Antoine Lavoisier – Phlogiston theory | Britannica

In the early stages of his research Lavoisier regarded the phlogiston theory as a useful hypothesis, but he sought ways either to solidify its firm experimental foundation or to replace it with an experimentally sound theory of combustion. In the end his theory of oxygenation replaced the phlogiston hypothesis, but it took Lavoisier many years and considerable help from others to reach this goal.

See All Good Facts. The phlogiston theory was discredited by Antoine Lavoisier between 1770 and 1790. He studied the gain or loss of weight when tin, lead, phosphorus, and sulfur underwent reactions of oxidation or reduction (deoxidation); and he showed that the newly discovered element oxygen was always involved.

Who disproved the phlogiston theory?

It was Antoine Lavoisier who disproved the Phlogiston Theory.

The Rise and Fall of the Phlogiston Theory of Fire

Preistley sought an explanation that would remain consistent with the phlogiston theory, so he speculated that this new gas was particularly good at absorbing phlogiston. Ordinary air, he suggested, already contained some phlogiston, and so could quickly be filled up with more phlogiston, making combustion, rusting, and breathing impossible.

: a theory in 18th century chemistry disproved by Lavoisier: every combustible substance is a compound of phlogiston and the phenomena of combustion are due to the liberation of phlogiston with the other constituent left as a residue the phlogiston theory thus provided a general explanation of the chemical processes of oxidation and reduction: oxidation was taken to be the liberation of phlogiston, and reduction combination with phlogiston — Linus Pauling
