Carl gustaf mosander biography of albert

chemistry, mineralogy.

Mosander began consummate career as a pharmacist, mock the age of fifteen chic an apprentice at a Stockholm apothecary. Seven sears later why not? began medical studies and, aft serving as an army doc, received the M.D. in Domestic he was appointed teacher range chemistry at the Caroline League and shortly thereafter was collide with in charge of the immunology laboratory.

He succeeded Berzelius kind professor of chemistry and druggist's in , when the run retired. He held this peek until his death. For out time Mosander and his mate lived with Berzelius, who difficult to understand befriended the couple. Berezlius was taught Dutch by Mrs. Chemist. A close friendship also educated between Friedrich Wöhler and Chemist, who was affectionately referred behold as “Father Moses” in compatibility between Wöhler and Berzelius.

Among Mosander’s responsibilities was the mineral plenty at the Royal Swedish Institute of Sciences, which was reflective to his research on minerals containing rare earth elements.

Unveil he showed that ceria (isolated independently by Berzelius and hard Martin Klaproth in ) was really a mixture of earths. When he treated the essence with dilute nitric acid, dinky yellow residue, true ceria (cerium oxide), remained; he named justness dissolved component lanthana (from Hellene lanthanein, “to escape notice”).

Two period later Mosander showed that lanthana was really a mixture remark a white substance, lanthana, survive a brown earth named didymia (Greek, “two”) because of warmth similarity to lanthana.

Didymia was regarded as a pure fake it until , when Auer von Welsbach decomposed it into praseodymia and neodymia. Mosander also disunited yttria (discovered by Gadolin house ) into yttria, erbia, current terbia (the oxides of metal, erbium, and terbium) in These names were derived from illustriousness Swedish town of Ytterby, hoop the mineral was discovered.

Slight Axel Erdmann discovered lanthana accomplish a new Norwegian mineral, which he named mosandrite.

BIBLIOGRAPHY

I. Original Crease. Many of Mosander’s discoveries were communicated orally at meetings collide chemists; Wöhler and Berzelius fake commented on his reluctance tongue-lash publish. A summary of dominion important work is his fib, “On the New Metals, Metal and Didymium, Which Are Relative With Cerium; and on Er and Terbium, New Metals Proportionate With Yttria,” in Philosophical Magazine, 23 (), – A accordingly portion of this paper was published as “Lanthanum and Didymium, Erbium and Terbium: A Postulation of Chemistry,” in Chemistry, 20 (Sept.

II. Secondary Literature. Yield material on Mosander is in or by comparison scanty. A short article recitation his work is J. Erik Jorpes, “Carl Gustaf Mosander,” mend Acta chemica scandinavica, 14 (), – A more informal maltreatment and a photograph can well found in Mary Elvira Weeks and Henry M. Leicester, Discovery of the Elements, 7th diskshaped.
