Lavoisier acid theory
WebAntoine-Laurent de Lavoisier (August 26, 1743 – May 8, 1794), the father of modern chemistry, 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 mass, recognized and named oxygen (1778) and hydrogen (1783), disproved the phlogiston theory, … 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.

WebIn 1772 Lavoisier discovered that when phosphorus or sulfur are burned in air the products are acidic. The products also weigh more than the original phosphorus or sulfur, suggesting the elements combine with something in the air to produce acids. But what? In 1774 Joseph Priestley visited Paris.

The concept of an acid-base reaction was first proposed in 1754 by Guillaume-François Rouelle, who introduced the word "base" into chemistry to mean a substance which reacts with an acid to give it solid form (as a salt).
