1.	Which of the following electrodes will act as anodes, which connected to Standard Hydrogen Electrode ?
Answer» `Al//Al^(+3)" "E^(Ө)=-1.66` `Fe//Fe^(+2)" "E^(Ө)=-0.44` `Cu//Cu^(+2)" "E^(Ө)=+0.34` `F_(2(g))//2F_((aq))^(-)" "E^(Ө)=02.87` Solution :Oxidation POTENTIAL of ELECTRODE is more than, it ACTS as ANODE.
