`E^(θ)` values of some redox couples are given below. On the basis of these values choose the correct option.
`E^(θ)` values: `Brt_(2)//Br^(-) = +1.90`
`Ag^(+)//Ag(s)=+0.80`
`Cu^(2+)//Cu(s)=+0.34, I_(2)(s)//I^(-)=+0.54`

A

Cu will reduce `Br^(-)`

B

Cu will reduce Ag

C

Cu will reduce `I^(-)`

D

Cu will reduce `Br_(2)`

Text Solution

Verified by Experts

From the available data, Cu(s) is the strongest redcuing agent and will reduce `Br_(2)`
`Cu(s)+Vr_(2)rarrCu^(2+)(aq)+2Br^(-)(aq)`

E^@ values of some redox couples are given below . On the basis of these values choose the correct option . E^@ value : Br_2|Br^(-) =+1.90,Ag^(+)|Ag (s) = +0.80 Cu^(2+)|Cu(s)=+0.34, I_2(s)|I^(-)=+0.54

The more positive the value of E^(θ) , the greater is the trendency of the species to get reduced. Using the standard electrode potential of redox coples given below find out which of the following is the strongest oxidising agent. E^(θ) values: Fe^(3+)//Fe^(2+) = +0.77 I_(2)(s)//I^(-) = +0.54 , Cu^(2+)//Cu = +0.34, Ag^(+)//A = 0.80V

Using the standard electrode potential, find out the pair between which redox reaction is not feasible. E^(θ) values: Fe^(3+)//Fe^(2+)=0.77, I_(2)//I^(-)=+0.54 , Cu^(2+)//Cu=+0.34, Ag^(+)//Ag=+0.80V
