electrorefining and electroplating

• electroplating

• electrorefining

  • extracting pure metal (mixture) electrolyte

• 

• 4. at the cathode: SRP: Li+, Na+, Fe2+

• metals that are more R(eactive) produce cations with lower SRP values

• as E cell = SRP of Fe2+, anything w/ lower SRP: does not reduce!

• anything more reactive than iron will just remain in solution.

• separation 1: anode (less reactive)

• separation 2: cathode (more reactive)

• 3 types of metal in the thingy

  • the metal itself
  • metal more reactive (higher sop)
  • metal less reactive (lower sop)
