How do sacrificial electrodes work?

  1. Mar 18, 2015 #1
    i have brass metal in contact with ammonia(liq), could someone help me identify the oxidation reaction?

    i thought the oxidation rxn was supposed to involve the ammonia and the copper, but that combination would lead to the copper being reduced, not oxidized. am i right?
    how exactly is copper losing its electrons?
