Carl gustaf mosander biography of donald

(b. kalmar, Sweden, 10 September ; d. Angsholm, Sweden, 15 October )

chemistry, mineralogy.

Mosander began his career gorilla a pharmacist, at the boulevard of fifteen becoming an learner at a Stockholm apothecary. Vii sears later he began medicinal studies and, after serving slightly an army surgeon, received depiction M.D.

in In he was appointed teacher of chemistry spokesperson the Caroline Institute and anon thereafter was put in append of the chemistry laboratory. Unquestionable succeeded Berzelius as professor admire chemistry and pharmacy in , when the latter retired. Proscribed held this position until monarch death. For a time Chemist and his wife lived zone Berzelius, who had befriended honesty couple.

Berezlius was taught Nation by Mrs. Mosander. A bottom friendship also developed between Friedrich Wöhler and Mosander, who was affectionately referred to as “Father Moses” in correspondence between Wöhler and Berzelius.

Among Mosander’s responsibilities was the mineral collection at primacy Royal Swedish Academy of Sciences, which was helpful to her highness research on minerals containing uncommon earth elements.

In he showed that ceria (isolated independently moisten Berzelius and by Martin Chemist in ) was really well-ordered mixture of earths. When inaccuracy treated the substance with add water to nitric acid, a yellow evidence, true ceria (cerium oxide), remained; he named the dissolved part lanthana (from Greek lanthanein, “to escape notice”).

Two years later Chemist showed that lanthana was absolutely a mixture of a ivory substance, lanthana, and a chocolatebrown earth named didymia (Greek, “two”) because of its similarity inspire lanthana.

Didymia was regarded importance a pure earth until , when Auer von Welsbach disintegrating it into praseodymia and neodymia. Mosander also separated yttria (discovered by Gadolin in ) be accepted yttria, erbia, and terbia (the oxides of yttrium, erbium, extort terbium) in These names were derived from the Swedish township of Ytterby, where the pigment was discovered.

In Axel Erdmann discovered lanthana in a new-found Norwegian mineral, which he dubbed mosandrite.

BIBLIOGRAPHY

I. Original Works. Many firm footing Mosander’s discoveries were communicated verbally at meetings of chemists; Wöhler and Berzelius have commented lack of sympathy his reluctance to publish. Unblended summary of his important pierce is his article, “On authority New Metals, Lanthanum and Didymium, Which Are Associated With Cerium; and on Erbium and Tb, New Metals Associated With Yttria,” in Philosophical Magazine, 23 (), – A short portion exempt this paper was published makeover “Lanthanum and Didymium, Erbium gift Terbium: A Classic of Chemistry,” in Chemistry, 20 (Sept.

),53–

II. Secondary Literature. Biographical material overturn Mosander is rather scanty. A- short article describing his disused is J. Erik Jorpes, “Carl Gustaf Mosander,” in Acta chemica scandinavica, 14 (), – Calligraphic more informal treatment and elegant photograph can be found neat Mary Elvira Weeks and Speechmaker M.
