AgNO_(3) solution can't be stored in copper vessels, because. . . .

Answer»

`E_(Ag^(+)|Ag)^(Theta) gt E_(Cu^(2+)|Cu)^(Theta)`
`E_(Ag^(+)|Ag)^(Theta) lt E_(Cu^(2+)|Cu)^(Theta)`
`E_(Ag^(+)|Ag)^(Theta) ne E_(Cu^(2+)|Cu)^(Theta)`
Ag is precious metal.

SOLUTION :Following reaction occur and `Cu^(2+)` ions are formed in solution.
`2AgNO_(3)+Cu_((S)) to Ag_((S)) +Cu_((aq))^(2+)+2NO_(3(aq))^(-)`
`E_(Ag^(+)|Ag)^(Theta)=0.80V, E_(Cu^(2+)|Cu)^(Theta)=0.34V`
So, reduction of `Ag^(+)` occur. And `Ag^(+)` is oxidizing AGENT. oxidation of `Cu^(2+)` occur and reaction occur for those WHOSE `E_(cell)^(Theta)` is LESS.
