2. A 19" century iron bridge is protected from corrosion by connecting it to a block of metal (sacritificial anode), which is replaced annually. The corrosion of iron, represented by the chemical equation: 2Fe(s) +2H;O() + O:(g) 2Fe(OH)2 Which of the following metals is best suited as sacrificial anode? a) Ag: Ag' +e ->Ag(s).E°=+0.80 V (b) Cd Cu (d) Mg: Mg +2e Mg(s), E° = -2.36 V Cd +2e+Cd(s), E° =-0.40 V Cu +2 Cu(s), E° = +0.34 V
