Using the standard electrode potentials Co2+(aq) + 2e → Co(s) E° = -0.28 V Fe2+(aq) + 2e → Fe(s) E° = -0.44 V choose the correct statement. Cobalt protects iron against corrosion by forming an insulating layer of oxide. Cobalt will protect iron against corrosion by cathodic protection. Cobalt is easier to oxidize than iron. Cobalt will be used as a sacrificial anode to protect iron against corrosion. Cobalt will serve as the cathode in an electrochemical cell when in...
