Thisi reaction is an example of chemical reaction .The breaking up of water into hydrogen and oxygen is actually a' chemical decomposition' reaction caused by passing an electric current through acidified water.
Michael Faraday, a well- known British experimental physicist, began his experiments on the passage of electricity through liquids (electrolyte) in 1834. He observed interesting chemical changes (effects) taking place when an electric current pass through an ionic solution. The resulting effects are known as chemical effects of current. Faraday called this phenomenon, of passage of electricity through liquids, as electrolysis. This is because; it causes chemical changes within the electrolyte.
