Is it safe to stir 1M `AgNO_(3`) solution with copper spoon? Given:`E^(@)Ag^(+)//ag=0.80V,E^(@)Cu^(2+)//Cu^(2+)//Cu=0.34V`

Answer

No

Explanation

Since `E_(Ag^(+),Ag)^(@)=+0.80V` is higher than `E_(Cu^(2+),Cu)^(@)=-E_(Cu^(2+),Cu)^(@)=-(0.34)=+0.34V therefore Ag^(+)` ions can easily accept electrons form Cu In other words the following reactin will occur
`Cu+2 Ag^(+)rarrCu^(2+)+2Ag`
Hence 1 M `AgNo_(3)` soluton cannot be stirred with a copper spoon
