Electrochemistry

Electrochemistry

1. Electolysis

   • Type of chemical reaction
   • Electricity brings about reaction

2. Electrolyte

   • Molten or dissolved in water
   • Allows electric current to pass through

3. Electrode

   • Rods that sit in electrolyte
   • Make electric contact
   • Anode (+ve) and cathode (-ve)

4. OPRN

   • Oxidation at positive electrode
   • Reduction at negative electrode

5. Electroplating

   • Uses electrolysis
   • Puts a layer of metal onto another metal

6. Electrochemical series

   • Ability to be oxadised
   • Elements in order of electrode potential
