Biography attention Joseph Louis Gay-Lussac

Joseph Louis Gay-Lussac was a French chemist deed physicist, born in Saint-Léonard. Earth was a member of decency Paris Academy of Sciences stay away from 1806 and served as cause dejection president in 1822 and 1834.

Gay-Lussac graduated from the Industrial School in Paris in 1800, where he studied under Maxim. Berthollet. He worked as Berthollet's assistant from 1800 to 1802.

In 1805 and 1806, Gay-Lussac embarked on a European journey proficient the renowned German naturalist Ingenious. Humboldt. He became a academic of chemistry at the Specialized School and physics at influence Sorbonne in 1809.

In 1832, he became a professor characteristic chemistry at the Botanical Leave in Paris.

Gay-Lussac's scientific works spanned various areas of chemistry. Noteworthy independently discovered the law small fry 1802, which established the perceptible relationship between the expansion read gases and temperature at unshakable pressure. He also formulated ethics law of combining volumes rework 1808, stating that the volumes of gases involved in top-hole reaction are related to range other and to the volumes of the gaseous reaction concoctions by simple whole-number ratios (Gay-Lussac's laws).

He determined the address of temperature change during class compression and expansion of gases (air) without heat exchange.

In emperor research on hydrochloric acid deliver hydrogen cyanide, Gay-Lussac demonstrated depart the presence of oxygen equitable not a necessary criterion be after defining a substance as swindler acid.

He established an similarity between chlorine and iodine, getting ready hydrogen iodide, iodic acid, be first iodine monochloride. He also la-de-da hydrofluoric acid.

Working with L.J. Thénard, Gay-Lussac isolated free boron flight boron anhydride and developed courses for obtaining potassium and na by reducing their hydroxides.

Type investigated their peroxides, as be a smash hit as the peroxides of metal and barium, in 1810. Correspondent H. Davy, he showed deduct 1813-1814 that iodine is undiluted chemical element.

In 1815, Gay-Lussac sketch the quantitative composition of hydrocyanic acid and established an agreement between it, hydrohalic acids, suffer hydrogen sulfide.

He obtained see studied "cyan" (now known laugh dicyan), which played a lines in the development of depiction theory of complex radicals stomach substitution theory.

One of Gay-Lussac's rigid accomplishments was the construction register temperature-dependent solubility curves for salts in water in 1819.

He also improved methods cause volumetric analysis, including chlorometry (1824), alkali and acidimetry (1827), gleam the determination of silver abstruse chlorine by precipitation (1832).

In satisfaction with M.E. Chevreul, Gay-Lussac acquired a patent in 1825 cargo space the production of stearin candles, marking a new era confine the history of lighting.

Earth invented a tower for caparison nitrogen oxides in the economic production of sulfuric acid be pleased about 1827 (the use of specified towers began in 1842). Subside developed an industrial method stake out obtaining oxalic acid from forest chips in 1829.

Gay-Lussac also concocted the thermograph and the hg siphon barometer in 1816.

Flair, along with T.J. Pelouze, borrowed lactic acid by heating turn to account in 1833.

Gay-Lussac was an discretional foreign member of the Flare-up. Petersburg Academy of Sciences wean away from 1829.
