applications

• sacrificial anode?

  Piece of metal (connected to another metal) that's more easily oxidised/ corroded than the metal bring protected from corrosion

  • oxidises preferentially
  • does not react with cold water
• what would be a sacrificial anode for iron

  A metal below Fe

  eg) Cr, Zn, Mn, Al, Mg

  • more positive E for oxidation / or more negative E for reduction, when compared to Fe
