Electrochemical Reactions

• Galvanic Cell 


  A cell in which chemical energy is converted into electrical energy.
• Oxidation 


  Oxidation is the loss of electrons.

  • An increase in oxidation number.
• Reduction 


  Reduction is the gain of electrons.

  • A decreasing in oxidation number.
• Oxidizing Agent


  A substance that is reduced/gains electrons.
• Reducing Agent 


  A substance that is oxidised/loses electrons.
• ANOX and REDCAT

  Anode: Electrode where oxidation takes place.

  Cathode: Electrode where reduction takes place.
• Electrolyte 


  A substance that dissolves in water to give a solution that conducts electricity.
• Electrolytic Cell 


  A cell in which electrical energy is converted to chemical energy.
• Electrolysis 


  The chemical process in which electrical energy is converted into chemical energy.
• AN-OX RED-CAT

  Anode = where Oxidation takes place, and oxidation is the loss of electrons.

  Cathode = where Reduction takes place, and reduction is the gain of electrons.
• Conductivity

  A measure of how well a solution can conduct electricity.
• Reducing agent:


  A substance that is oxidized.
