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 hydronium ions that appr

The Basics of Hydrogen Electrolysis

Water Electrolysis is done through the use of an electrolyser, a device that contains two electrodes and an electrolyte separating them. When an electric current is applied between the

Electrolysis of water

Indirect seawater electrolysis involves two steps: desalting seawater using a pre-treatment device and then producing hydrogen through traditional water electrolysis.
