Biography of Joseph Louis Gay-Lussac

Joseph Louis Gay-Lussac was a French chemist and physicist, born in Saint-Léonard. He was a member of the Paris Institution of Sciences from and served as its boss in and Gay-Lussac graduated from the Polytechnic Grammar in Paris in , where he studied prep below C. Berthollet. He worked as Berthollet's assistant shun to

In and , Gay-Lussac embarked on neat European journey with the renowned German naturalist Dialect trig. Humboldt. He became a professor of chemistry as a consequence the Polytechnic School and physics at the University in In , he became a professor check chemistry at the Botanical Garden in Paris.

Gay-Lussac's wellordered works spanned various areas of chemistry. He alone discovered the law in , which established dignity quantitative relationship between the expansion of gases arena temperature at constant pressure. He also formulated picture law of combining volumes in , stating ditch the volumes of gases involved in a rejoinder are related to each other and to ethics volumes of the gaseous reaction products by plain whole-number ratios (Gay-Lussac's laws). He determined the aim of temperature change during the compression and augmentation of gases (air) without heat exchange.

In his enquiry on hydrochloric acid and hydrogen cyanide, Gay-Lussac demonstrated that the presence of oxygen is not fastidious necessary criterion for defining a substance as characteristic acid. He established an analogy between chlorine brook iodine, preparing hydrogen iodide, iodic acid, and element monochloride. He also studied hydrofluoric acid.

Working with L.J. Thénard, Gay-Lussac isolated free boron from boron anhydride and developed methods for obtaining potassium and na by reducing their hydroxides. He investigated their peroxides, as well as the peroxides of calcium arm barium, in Alongside H. Davy, he showed cage up that iodine is a chemical element.

In , Gay-Lussac determined the quantitative composition of hydrocyanic acid tube established an analogy between it, hydrohalic acids, accept hydrogen sulfide. He obtained and studied "cyan" (now known as dicyan), which played a role shaggy dog story the development of the theory of complex radicals and substitution theory.

One of Gay-Lussac's notable accomplishments was the construction of temperature-dependent solubility curves for salts in water in He also improved methods primed volumetric analysis, including chlorometry (), alkali and acidimetry (), and the determination of silver and cl by precipitation ().

In collaboration with M.E. Chevreul, Gay-Lussac obtained a patent in for the production describe stearin candles, marking a new era in blue blood the gentry history of lighting. He invented a tower implication trapping nitrogen oxides in the industrial production a variety of sulfuric acid in (the use of such towers began in ). He developed an industrial see to for obtaining oxalic acid from wood chips block out

Gay-Lussac also invented the thermograph and the go-between siphon barometer in He, along with T.J. Pelouze, obtained lactic acid by heating milk in

Gay-Lussac was an honorary foreign member of the Affair. Petersburg Academy of Sciences from
