Factitious air

In 1766 the Royal Society published Cavendish s Three Papers Containing Experiments on Factitious Air, describing his experiments with hydrogen, which is produced when metals are dissolved in acids. [Pg.96]

Containing Experiments on Factitious Air. His presentation is a model of clarity and simplicity well illustrated by his opening sentence By factitious air, I mean in general any kind of air which is contained in other bodies in an unelastic state, and is produced from thence by art. In the three parts Cavendish describes his experiments relating to inflammable air, fixed air, and the air produced by fermentation and putrefaction. [Pg.156]

Van Helmont s chemical experiments and his chemical theories exerted a powerful influence on the chemists of his century. No chemist is cited more frequently nor with higher respect. Yet, his theory of the two elements, air and water, did not, with many, replace the four Aristotelian elements, nor the three principles, though the latter had by this time been frequently elaborated into five, sulphur, mercury, salt (the active principles), and phlegm (water) and earth (the passive principles). The suggestion of the rational and desirable term gas which he used, was ignored by his early successors. Boyle, Boerhaave, and Priestley used instead the terms artificial air, factitious air, ... [Pg.385]

The first publication by Cavendish was on Factitious Airs, three papers read before the Eoyal Society in 1766. The term factitious air was used in the same sense as by Boyle a century earlier. Cavendish says ... [Pg.472]

Factitious air refers to gases derived from heating or other chemical actions on solids. Thus, hydrogen appears to be liberated from an active metal upon addition of acid and is, therefore, a factitious air. ... [Pg.277]

Cavendish s first paper in fact was on factitious airs, that is, gases fixed in some material but capable of being freed, such as carbon dioxide in carbonates. One of these factitious airs was his inflammable air, hydrogen gas, which he collected from metals treated with acid. [Pg.143]

Smeth objected (with reason) to the name fixed air , since it has no true relation to common air. It is the astus of the ancients. Van Helmont s gas syl-vestre, and Boyle s factitious air, which occurs in the Grotto del Cane and other caves. It varies with the body from which it is disengaged and does not exist ready formed in bodies it is a miasma composed of the detritus from the collision of the particles of solids and liquids, being formed only by the violent... [Pg.87]
