Q7.
Using the standard electrode potential of redox couples given below find out which of the following is the strongest oxidising agent.
E0 values: Fe3+/Fe2+ = +0.77; I2/I-(s) = +0.54; Cu2+/Cu = +0.34; Ag+/Ag = +0.80
Answer : Option B
Explaination / Solution:
The more positive the value of E0, the greater is the tendency of the species to get reduced, therefore Ag+/Ag = +0.80 is strongest oxidising agent.
