Question:
The more positive the value of Eᶱ, the greater is the tendency of the species to get reduced. Using the standard electrode potential of redox couples given below to find out which of the following is the strongest oxidising agent. Eᶱ 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
Solution:
Option (iv) Ag is the answer.
