Production of Elements/Molten Salt Electrolysis

  • Requires molten ionic compounds

  • Forms metals at the cathode

  • Forms non metals at the anode

2
New cards

Molten

Some metals react with water which is why it isn’t aqueous

3
New cards

Refining of Metals (Electrofining)

  • Impure solid metals are oxidized to aqueous cations

  • Anode = impure metal

  • Cathode = pure metal

Electroplating

  • The process of covering one metal with another

  • Cover the cathode (CC) to protect from rusting

  • Chroming is commonly used on cars
