The `E^(Theta)` for `Cl_(2)//Cl^(-)` is `+1.36` for `I_(2)//I^(-)` is `+0.53, " for " Ag^(+)//Ag` is `+0.79, Na^(+)//Na` is `-2.71` and for `Li^(+)//Li` is `-3.04` Arrange the following ionic spects in decreasing order of reducing strength:
`I^(-), Ag, Cl^(-), Li, Na`

Text Solution

Verified by Experts

The more negative or less positive is the electrode potential, more is the reducing strength of the species. Since the electrode potentials increase in the order: LI (-3.04 .V) < Na (- 2.71 V) <1. (+ 0.53 V) < Ag (+0.79 V) Na >> Ag > cr
