Hydrogen Production From Alkaline Water

The principle of hydrogen production from alkaline water: direct current is introduced into the aqueous solution of strong alkali, and under the action of direct current, water molecules are decomposed into hydrogen ions and hydroxide ions, and the hydroxyl at the anode loses electrons to produce oxygen; At the cathode, hydrogen ions gain electrons to produce hydrogen. The reaction formula is:

On the cathode: 4H2O+4e→2H2↑+4OH

On the anode: 4oh ―― 4e→ 2h2o+O2 ↑.

Total reaction formula: 2H 2O=2 H2↑+O2↑.
