|
 |
(1775): List of experiments. The tenth item reads "revivication du mercure précipté per se."
|
|
|
(1775-02-28): Experiments at Montigny on fictitious airs. Experiment to test the similarity of the inflammable vapor of alcohol and ether with the "air inflammable" produced by the action of vitriolic acid and copper.
|
|
|
(1775-03): Experiments on the behavoir of fixed alkali with charcoal to see if carbon facilitates the separation of fixed air.
|
|
|
(1775-03): Action of fuming nitric acid on sulphur; study of the gas released. "Le gaz fermentait … avec l'air commun."
|
|
|
(1775-03): "Air sulfureux volatil" from reaction of charcoal and vitriolic acid; no gas produced from reaction of "spath calcaire" and charcoal.
|
|
|
(1775-03): Lavoisier is seeking new gases in reaction where fumes are produced: nitrous air from minum; fuming liquor of Libavius; "air aceteux" from crystals of Venus and from fuming liquor of Boyle.
|
|
|
(1775-03-31): Experiments on mercury repeated in presence of La Rochefoucauld, Trudaine de Montigny, Macquer and Cadet. (Observations sur la physique, 1775, vol. 5, p. 429).
|
|
|
(1775-04): Experiment on heating chalk with charcoal and on reduction of iron oxides.
|
|
|
(1775-04): Experiment on sample of traprock (metamorphosed volcanic rock) brought by the duc of La Rochefoucauld; fusion with borax and salt.
|
|
|
(1775-04): Experiment on iron oxide (reduction?) made in Lavoisier's furnace by Guyton de Morveau.
|
|
|
(1775-04-08): Experiments with La Rochefoucauld, Macquer, Cadet, Desmarets and Le Roy. Minium and sel ammoniac; vapor and air do not support combustion, nor precipitate limewater.
|
|
|
(1775-04-08): Experiments on inflammable air, burning it in fixed air and in air enclosed vessels. Notes that it burns only in proportion to the air introduced. Asks what remains when completely burned.
|
|
|
(1775-09): Begins work on saltpetre. Analysis of "cendres salpetriers" and "cendres de tourbe" (peat ash)
|
|
|
(1775-09-26): Mother liquor of nitre - its decomposition by potash.
|
|
|
(1775-10-04): Solution of white zinc oxide in nitric acid.
|
|
|
(1775-10-28) (1775-10-29): Experiments done at Montigny: minium and sulphuric acid and nitric acid, minium and sulphur etc. Also reaction of sulphurica cid and "huile essentielle" producing a gas which burns a blue flame (CO). Further work on "cendres des
