Soft cover. Condizione: Very Good. GRAHAM, Thomas. "Researches on the Arseniates, Phosphates, and Modifications of Phosphoric Acid" from from "Philosophical Transactions" 1833, London, Richard Taylor, pp 253-284, 30cm. Disbound from a larger volume. "Graham s major contribution to inorganic chemistry is his paper Researches on the Arseniates, Phosphates, and Modifications of Phosphoric Acid, in which he elucidated the differences between the three phosphoric acids. This research and the style of the paper are reminiscent of Joseph Black s work on magnesia and the alkalies carried out in Glasgow eighty years earlier. Graham s discovery of the polybasicity of these acids provided Justus Liebig with the clue to the modern concept of polybasic acids. Of this classic work the eminent German chemist and historian of chemistry Albert Ladenburg has said, so much has seldom been accomplished by a single investigation. Nevertheless, J. J. Berzelius insisted that the three phosphoric acids were isomers of P2 O5 and as late as 1843 he wrote that Graham s point of view lacks justification in several respects. --Complete Dictionary of Scientific Biography Online, vol. 5, Charles Scribner's Sons, 2008, pp. 492-495. FNCH23. [++] "Thomas Graham (1805-1869) is known as the founder of colloidal chemistry and for his fundamental research on the nature of phosphoric acid and phosphates, diffusion of gases, liquids, and solutions, adsorption of gases by metals, dialysis, osmosis, mass transfer through membranes, and the constitution of matter."-- Jaime Wisniak, "Thomas Graham.
