Aqueous Electrolysis

• What is another way of saying aqueous?

  Dissolved, In Solution
• In Aqeuous solutions at the cathode, the least reactive element is formed. Either Hydrogen or a Metal.
• In Aqeuous solutions at the CATHODE

  
  

  • If metal less reactive than hydrogen = metal formed.
  • If metal more reactive than hydrogen = hydrogen formed.
• In Aqeuous solutions at the ANODE, either Oxygen or a halogen is formed.
• In Aqeuous solutions at the ANODE

  
  

  • If Halide present, halogen is formed.
  • If Halide not present, OH- will be produced forming Oxygen.
• In Aqueous Electrolysis, because aqueous means dissolved in water. Water is formed. Water is also ionised into OH- and H+ ions.
