O coulômetro de sódio: um experimento interessante de eletroquímica
The diffusion of sodium through glass, the basis of a sodium coulometer, was revised and modified for the application to present-day light bulbs. Low pressure inert gas-filled incandescent lamps are useless to attain satisfactory results. The inclusion of a 450 V power supply in series with the electrolysis cell provided sufficient potential to overcome the effect of the inert gas molecules inside the bulb.
