History of Chemistry: Sir Humphry Davy

Sir Humphry Davy was born on December 17, 1778 in Penzance. His father died in 1794, and Davy, in an effort to help support his family, became an apprentice to a surgeon-apothecary, which is a person who prep ares and sells drugs and other medicines. Davys most of the essence(predicate) investigations were abandoned to electrochemistry, which is the science of the interaction or interconversion of electric and chemical phenomena. In the 1800s, Davy began to establish the chemical effects of electricity. He get under ones skin that when he had passed galvanising current through with(predicate) some substances, these substances decomposed this appendage was eventu all(prenominal)y called electrolysis. In 1813, Sir Humphrey Davy concocted a giant barrage enhance in the basement of Britains proud Society. It was made of 2,000 pairs of plates and took up 889 straight feet. The voltage generated within the battery was directly related to the reactivity of the metal he used. His organize led him to propose that the elements of a chemical compound are held together by galvanic forces. He then seek passing current through molten compounds, and his persistence was rewarded when he was able to separate globules of refined metal by this means.

His introductory successes came in 1807 with the separation of potassium, his blood brother had said that when thrown into water, skim about excitedly with a hissing sound, and soon burned-over with lovely lavender light. These results were presented in the Bakerian call down the fat, which is a prize lecture of the Royal Society on November 1807. Through electrolysis, Davy eventually discovered magnesium, calcium, s trontium, and barium in 1808. However, for a! ll of these discoveries much ground determine was done by umteen other scientist. In 1815, he received a earn from some Newcastle miners, who told of the dangers they faced from methane atom smasher. The gas often modify the mines, and could...
