Redox reactions

• Can Electrolysis of Aqueous NaCl Produce Sodium Metal?
  Aqueous sodium chloride electrolysis produces hydrogen and sodium hydroxide, not sodium metal: water is reduced first, and sodium reacts with water.
• Is Twice as Much Hydrogen Produced as Chlorine in Brine Electrolysis?
  Brine electrolysis ideally produces equal moles and gas volumes of hydrogen and chlorine; the familiar 2:1 hydrogen ratio is for water electrolysis.
