|
 |
(1773-06-28): Combustion of minium by charcoal. Performs a metallic reduction for M. de Trudaine (obviously of minium and charcoal).
|
|
|
(1773-06-30): Combustion of phosphorous over mercury with a burning glass.
"Il aurait été bien inéressant de rassembler cet acide dans cet état pour le peser et avoir l'augmentation du poids pour voir si elle était proportionelle à l'absorption." Difficu

|
|
(1773-06-30): Experiments on lime (chaux) and fixed air
|
|
|
(1773-07-01): Air in which he burned phosphorous on June 27 extinguishes a candle, does not asphyxiate a bird, does not make lime water turbid. The error on bird passed into published Opuscules.
|
|
|
(1773-07-01) (1773-07-03): Experiments on sodium carbonate and air given off.
|
|
|
(1773-07-14): Dissolution of mercury by nitric acid, then precipitation by chalk (craie), lime (chaux), sodium carbonate and hydroxide (soude, carbonate et alcali); then the same experiment carried out on a solution of iron in nitric acid
|
|
|
(1773-07-16): Experiments with burning glass
|
|
|
(1773-07-17): Detonation of nitre with burning glass
|
|
|
(1773-07-19): Records decrease in weight of ammonia on the addition of lime (perhaps has confused ammonia with carbon dioxide). Performed with hydrometer.
|
|
|
(1773-07-20): Combustion of phosphorous. Experiment described in the Opuscules. "Il y a diminution de volume de l'air pendant la combustion du phosphore et je l'ai attribuée jusqu'ici à la fixation de ce même air, mais ne pourrait-il pas arriver que ce fu
|
|
|
(1773-07-22): Combination of water with the air in which he has burned phosphorous. Asks if decrease in volume might not be due to humidity of air.
|
|
|
(1773-07-22): Precipitation of "terre calcaire" (dissolved in nitric acid) by adding alkali volatile concret-caustique
|
|
|
(1773-07-22): Reduction of the calx of mercury precipitated by chalk. "L'air s'est dilaté comme à l'ordinaire mais sur la fin l'eau est remontée sensibliment." Formation of a little liquid mercury. No precise conclusion.
|
|
|
(1773-07-26): Nitric acid, varying degrees of acidity; amount of lime necessary to neutralize. Experiments on fixed air. Density of water solutions with hydrometer. Mixes water solution of fixed air with limewater
|
|
|
(1773-07-31): Reduction of lead calx by charcoal. Proportion of lead in minium; examination of the air resulting from the reduction. Rat placed in the gas. No results given.
|
|
|
(1773-08): Experiments involving fixed air and ammonia which he may well have confused.
|
|
|
(1773-08-05) (1773-08-14): Experimentation with the burning glass
|
|
|
(1773-09-25) (1773-09-29): Verification of Lavoisier's experiments by commissioners. Lavoisier performs them in presence of Trudaine, Le Roy, Montigny, Macquer and Cadet.
BNF Nuov. Acq. 5153.
|
|
|
(1773-09-29): Identifies gas produced by burning charcoal as fixed air (limewater test)
|
|
|
(1773-10): Calcination of diamonds and charcoal with the burning glass. Calcination of charcoal in iron flasks and tubes; finds that rust of the iron instruments is reduced by charcoal.
|
|
|
(1773-10): Calcination of lead over mercury with a burning glass. A candle is extinguished in the residual gas
|
|
|
(1773-10-22): Experiment on diamond. Heated with burning glass in atmosphere of fixed air.
|
|
|
(1773-10-29): Reduction of minium by charcoal in an iron tube. The residual gas is saved from October 29 1773 to May 27, 1774. It asphyxiates a bird, extinguishes a candle.
|
|
|
(1773-11-13): Reactions of phosphoric acid and of its salts of calcium (chaux), magnesium etc. Degree of affinity of phosphoric acid: it is displaced from its salts by sulphuric acid and nitric acid.
|
| |
1774 |
|
|
(1774-02-05) (1774-02-15): Calcination of tin and lead in a closed vessel, no gain in weight; upon admission of air gain of weight equal to that of metal.
