The more positive the value of `E^(Ө)`, the 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_(Fe^(+3)//Fe^(+2))^(Ө)=+0.77"volt",E_(I^(2)//I^(-))^(Ө)=+0.54"volt"`
`E_(Cu^(+2)//Cu)^(Ө)=+0.34"volt",E_(Ag^(+)//Ag)^(Ө)=+0.80"volt"`

Options

A. `Fe^(+3)`
B. `I_(2(s))`
C. `Cu^(+2)`
D. `Ag^(+)`

Answer

D

Explanation

Since, `E^(@)` of he redox couple `Ag^(+)//Ag` is the most positive, i.e., +0.80 V, therefore, `Ag^(+)` is strongest oxidising agnet.
