This work led directly to the isolation of sodium and potassium from their compounds (1807) and of the alkaline-earth metals magnesium, calcium, strontium, and barium from their compounds (1808). WebSir Humphry Davybelieved that chemical union was electrical in nature- and so, a strong electric current might be able to overcome the forces binding compounds together, and lead to the isolation of new elements. In 1807 he tested this hypothesis on caustic potash (potassium hydroxide, KOH) and caustic soda (sodium hydroxide, NaOH), which

The remarkable Cornish chemist Humphry Davy also started experiments in electrolysis in 1800. WebPotassium was isolated in 1807 by Sir Humphry Davy, who obtained it through the electrolysis of very dry molten caustic potash (KOH, potassium hydroxide). Potassium collected at the cathode. Potassium was the first metal isolated by electrolysis. Davy isolated sodium by a similar procedure later in 1807.
