(1774-11-29): Further notebook entry: reflection on the multiplicity of airs and changes of physical state. In particular Lavoisier has the idea that all substances in nature "peuvent se présenter à nos yeux dans trois états différents, sous forme solide, sous forme liquide et sous forme expansive." Acids are formed by dissolution of air in water; nitrous air in order to give "acide nitreux" (nitric acid) must first combine with something in the air. |
