The overall balanced equation for the process is: OH - ions are attracted to the anode, lose electrons and form oxygen gas.H+ ions are attracted to the cathode, gain electrons and form hydrogen gas.If water is acidified with a little dilute sulfuric acid: These ions are formed when a small proportion of water molecules naturally dissociate. Water is a poor conductor of electricity, but it does contain some hydrogen ions, H +, and hydroxide ions, OH. doi:10.1023/A:1026441532352įontes E, Håkansson B, Herlitz F, Lindstrand V (2012) Process for producing alkali metal chlorate.Electrolysis of solutions Electrolysis of acidified water Roue L, Guay D, Schulz R (2000) Hydrogen electrosorption in nanocrystalline Ti-based alloys.
