Why one of history's greatest scientists failed to isolate fluorine
In short: Even a genius like Michael Faraday faced insurmountable obstacles. This video explores his unsuccessful attempt to isolate the highly reactive element fluorine using electrochemical techniques, a challenge that remained unsolved for decades.
Between 1834 and 1835, Michael Faraday attempted to isolate fluorine by applying the same electrochemical methods Humphry Davy had used to isolate sodium and potassium in 1807. Working with the dangerous molten lead fluoride (PbF2), Faraday's efforts were thwarted by the element's extreme reactivity; as soon as fluorine was released, it reacted immediately with oxygen in the air.
This scientific hurdle persisted for nearly half a century until French chemist Henri Mossain finally succeeded in 1886, an achievement that earned him the Nobel Prize.
