Michael
Faraday was born in London in 1791 and died in August, 1867. He acted as
an assistant to Humphrey Davy at the Royal Institution, and in 1825 he
was appointed Director of the laboratory. He conducted seminal experiments
in electricity and electromagnetismwhich were published in "Experimental
Researches in Electricity" between 1839 and 1855. His "Experimental Researches
in Chemistry and Physics" was published in 1858.
The
Faraday constant, F, is defined as the number of Coulombs required to liberate
1.008 grams of hydrogen in an electrochemical reaction. The atomic weight
of Hydrogen is 1.008 and it has unit valency. F = 9.6490 x 104
coulombs. This is the charge associated with Avogardro's number of electrons
(6.023 x 1023 x 1.602 x 10 -19). |
