1.	Which of the following electrodes will act as anodes, when connected to Standard Hydrogen Electrode ?
Answer» `Al//Al^(3+) ""E^@=-1.66V` `Fe//Fe^(2+) ""E^@=-0.44V` `Cu//Cu^(2+) ""E^@=-0.34V` `F_2(G)2F^(-)(aq) " "E^@=+2.87V` SOLUTION :The electrodes having negative ELECTRODE potentials are stronger reducing agents than `H_2` gas and therefore , will ACTS as anodes.
