Which of the following electrodes will act as anodes, which connected to Standard Hydrogen Electrode?A. `Al//Al^(3+)" "E^(Θ) =-1.66`B. `Fe//Fe^(2+)" "E^(Θ)=-0.44`C. `Cu//Cu^(2+)" "E^(Θ)=+0.34`D. `F_(2)(g)//2F^(-)(aq)" "E^(Θ)=02.87` |

Answer» Correct Answer - a,b All electrodes which have negative electrode potentials are stronger reducing agents than `H_(2)` gas and hence acts as anodes when connected to standard hydrogen electrodes. Thus, `Al^(3+)//Al(E^(Θ)=-1.66V)` and `Fe^(2+)//Fe(E^(Θ)=-0.44V)` act as anode. |
