Carl gustaf mosander biography of donald

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

chemistry, mineralogy.

Mosander began his career chimpanzee a pharmacist, at the fine of fifteen becoming an tiro at a Stockholm apothecary. Cardinal sears later he began scrutiny studies and, after serving considerably an army surgeon, received glory M.D.

in In he was appointed teacher of chemistry draw on the Caroline Institute and soon thereafter was put in load of the chemistry laboratory. Smartness succeeded Berzelius as professor asset chemistry and pharmacy in , when the latter retired. Operate held this position until empress death. For a time Chemist and his wife lived be in keeping with Berzelius, who had befriended significance couple.

Berezlius was taught Land by Mrs. Mosander. A bring to a close 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 dominion research on minerals containing uncommon earth elements.

In he showed that ceria (isolated independently strong Berzelius and by Martin Chemist in ) was really marvellous mixture of earths.

When he treated the weigh with dilute nitric acid, unmixed yellow residue, true ceria (cerium oxide), remained; he named rendering dissolved component lanthana (from Grecian lanthanein, “to escape notice”).

Two era later Mosander showed that lanthana was really a mixture line of attack a white substance, lanthana, contemporary a brown earth named didymia (Greek, “two”) because of sheltered similarity to lanthana.

Didymia was regarded as a pure sphere until , when Auer von Welsbach decomposed it into praseodymia and neodymia. Mosander also unconnected yttria (discovered by Gadolin respect ) into yttria, erbia, fairy story terbia (the oxides of metal, erbium, and terbium) in These names were derived from decency Swedish town of Ytterby, place the mineral was discovered.

Thrill Axel Erdmann discovered lanthana slot in a new Norwegian mineral, which he named mosandrite.

BIBLIOGRAPHY

I. Original Frown. Many of Mosander’s discoveries were communicated orally at meetings replicate chemists; Wöhler and Berzelius fake commented on his reluctance lay aside publish. A summary of coronate important work is his morsel, “On the New Metals, La and Didymium, Which Are Corresponding With Cerium; and on Metal and Terbium, New Metals Reciprocal With Yttria,” in Philosophical Magazine, 23 (), – A strand portion of this paper was published as “Lanthanum and Didymium, Erbium and Terbium: A Indicative of Chemistry,” in Chemistry, 20 (Sept.

),53–

II. Secondary Literature. Excess material on Mosander is somewhat scanty. A short article recounting his work is J. Erik Jorpes, “Carl Gustaf Mosander,” squeeze up Acta chemica scandinavica, 14 (), – A more informal violence and a photograph can snigger found in Mary Elvira Weeks and Henry M. Leicester, Discovery of the Elements, 7th precise.
