Lavoisier acid theory
WebGreek for \acid former". Lavoisier had assigned this name to the new gaseous element that Joseph Priestly had discovered a few years earlier as the essential substance that supports combustion. Many combustion products (oxides) do give acidic solutions, and oxygen is in fact present in most acids, so Lavoisier’s mistake is understandable. Web27 okt. 2024 · In 1778, Lavoisier put forward his new theory of combustion by which combustion was the reaction of a metal or an organic substance with that part of common air he termed “eminently respirable”.

In the intervening period, Lavoisier had ample time to repeat some of Priestley's latest experiments and perform some new ones of his own. In addition to studying Priestley's dephlogisticated air, he studied more thoroughly the residual air after metals had been calcined. He showed that this residual air supported neither …
WebAntoine-Laurent de Lavoisier (August 26, 1743 - May 8, 1794) was a French nobleman prominent in the histories of chemistry, finance, biology, and economics. He stated the first version of the law of conservation of matter, recognized and named oxygen (1778), disproved phlogiston theory, and helped to reform chemical nomenclature. WebLavoisier remarque que cette substance n’est pas respirable : un animal ne peut y vivre (azote = a- zoos -, privatif de vie). Dans un second temps, Lavoisier fait chauffer les flocules rouges : c’est la réaction inverse, avec dégagement d’un gaz « éminemment respirable » (l’oxygène), qui ravive la flamme d’une bougie quasi éteinte.
