Discovery of Lithium
Dr. Doug Stewart
Lithium was discovered before Johan Arfvedson in 1817, during an enquiry of petalite
(LiAlSi4O10).
He create the petalite contained ¡°silica, alumina and an alkali.¡± (1)
The new alkali metal in the petalite had unique properties.
It required more acid to undo it than sodium and its carbonate was no more than sparingly soluble in o ¨C distant from sodium carbonate.
The modern alkali differed from potassium because it did not persuade a provoke with tartaric acid.
Arfvedson tried to mount a sterling swatch of the recent metal past electrolysis, but he was unsuccessful; the battery he cast-off was not stalwart enough. (2)
The sanitary metal was isolated the following year nearby both William Brande and Humphry Davy working independently.
Davy obtained a small volume of lithium metal aside electrolysis of lithium carbonate. (3)
He noted the new particular had a red warmth color somewhat like strontium and produced an alkali colloidal suspension when dissolved in water.
In days less safety-conscious than the show, Brande said of lithium, ¡°its solution tastes acrid like the other fixed alkalies.¡± (4)
By 1855 Robert Bunsen and Augustus Matthiessen were independently producing the metal in large quantities not later than electrolysis of molten lithium chloride.
Lithium¡¯s identify is derived from the Greek confab ¡®lithos¡¯ meaning, ¡®stone.¡¯
