The more positive the value of E, 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.

E values: Fe3+/Fe2+=+0.77I2(s)/I-=+0.54;Cu2+/Cu=+0.34; Ag+/Ag=0.80 V

1. Fe3+

2. I2(s)

3. Cu2+

4. Ag+

Hint: High reduction potential value strongest is the oxidisng agent
The given values are as follows:
E° values of
Since, E° of the redox couple Ag+/Ag is the most positive, i.e., 0.80 V, therefore Ag+ is the strongest oxidising agent.
