Text Appearing Before Image:
Fig. 7C>. Coupe de la lampe de lappareil deLavoisier lhuile, forme avec elle, en loxygénant, du gaz acide carbonique et de leau.Une partie de cette eau se condense sur les parois du bocal A; une autre partieest tenue en dissolution dans lair par la chaleur de la combustion ; mais cetair, qui est poussé par la pression quil reçoit du gazomètre, est obligé de pas-ser par le tuyau 12, 13, 14 et 15, doù il est conduit dans la bouteille 16 et dansle serpentin 17 et 18, où leau achève de se condenser à mesure que lair se re-froidit. Enfin, si quelque peu deau restait encore en dissolution dans lair, elleserait absorbée par le sel déliquescent contenu dans le tube 19 et 20.
Text Appearing After Image:
462 HISTOIRE DE LA CHIMIE « Toutes les précautions quon vient dindiquer nont dantre objet que de re-cueillir leau qui sest formée, et den déterminer la quantité : il reste ensuite àévaluer lacide carbonique et le gaz azote. On y parvient au moyen des bouteil-les 22 et 25, qui sont à moitié remplies de potasse en liqueur et dépouillées da-cide carbonique par la chaux. Lair qui a servi à la combustion y est conduitpar les tuyaux 20, 21, 23 et 24, et il y dépose le gaz acide carbonique quil con-tient. On na représenté dans celte figure, pour la simplifier, que deux bouteil-les remplies de potasse en liqueur; mais il en faut beaucoup davantage, et jene crois pas quon puisse en employer moins de neuf. Il est bon de mettre dansla dernière de leau de chaux, qui est le réactif le plus sur et le plus sensiblepour reconnaître lacide carbonique : si elle ne se trouble pas. on peut être as-suré quil ne reste pas de gaz acide carbonique dans lair, du moins en quantitésensible.
