The more positive the value of EV , the greater is the tendency of the species to get reduced. Using the standard electrode potential of redox couples given below find out which of the following is the strongest oxidising agent.

EV values: Fe3+/Fe2+ = + 0.77; I2 (s)/I– = + 0.54;

Cu2+/Cu = + 0.34; Ag+/Ag = + 0.80V

(i) Fe3+

(ii) I2 (s)

(iii) Cu2+

(iv) Ag+

    This is a Multiple Choice Questions as classified in NCERT Exemplar

    Option (iv) is the correct answer

    The strongest oxidising agent means it has greater tendency to oxidise other species and itself gets easily reduced. So higher the E? values, stronger is the oxidising agent it is. Thus, Ag+ having the highest positive E?   value among the given systems, is the strongest oxidising agent.
