Electrolysis Is an Electrochemical Process In Whichelectrical Energy Is the Driving Force of Chemical Reactions. Substances Aredecomposed, By Passing a Current Through Them. the First Observation of Thisphenomenon Was Recorded In 1789. Nicholson and Carlisle Were the First Whodeveloped This Technique Back In 1800 and By the Beginning of the 20Th Centurythere Were Already 400 Industrial Water Electrolysis Units In Use. As Mentioned Before, Water Is Decomposed to Hydrogen Andoxygen, By Passing a Current Through It In the Presence of Suitable Substances,Called Electrolytes. Electric Current Causes Positively Charged Hydrogen Ionsto Migrate to the Negatively Charged Cathode, Where a Reduction Takes Place Inorder to Form Hydrogen Atoms. the Atoms Formed Then Combine to Form Gaseoushydrogen Molecules (H2). on the Other Hand, Oxygen Is Formed at the Otherelectrode (The Positively Charged Anode). the Stoichiometry of the Reaction Istwo Volumes of Hydrogen to One Volume of Oxygen. the Most Important Part of Theconstruction of Electrolysis Units Is to Use Adequate Electrodes to Avoidunwanted Reactions, Which Produce Impurities In the Hydrogen Gas. Anothernecessary Component of Such a Unit Is a Separating Membrane That Allows Thepassage of Ions, or Electrons and Not Oxygen, or Hydrogen Atoms. This Membraneallows the Gases to Be Kept Separate In Order to Avoid the Risk of an Explosivemixture Being Formed In the Electrolysis Unit. In the Initial Discovery of Electrolysis, an Acidic Waters ...
