Electrolysis of water
OverviewElectrolyteHistoryPrinciplesEquationsThermodynamicsTechniquesApplications
Electrolysis in pure water consumes/reduces H cations at the cathode and consumes/oxidizes hydroxide (OH ) anions at the anode. This can be verified by adding a pH indicator to the water: Water near the cathode is basic while water near the anode is acidic. The hydroxides OH that approach the anode mostly combine with the positive hydronium ions (H3O ) to form water. The positive h…
