  • If we connect an electrolyzer filled

  • with distilled water to a source of direct current,

  • we can observe a slow evolution of gases.

  • After some time, we notice that the volume of the gas

  • released at the cathode is double that of the gas

  • formed at the anode.

  • To identify the gassiest products of the reaction,

  • we collect each gas in and check its behavior

  • in the presence of a glowing splint.

  • The characteristic cracking sound proves that

  • the gas released at the cathode is hydrogen.

  • The ignition of the glowing splint is evidence of the gas

  • collected from the anode is oxygen,

  • which supports combustion.
