Is it safe to stir 1 M AgNO_(3) solution with a copper spoon ? Given E_(Ag^(+),Ag)^(@)=0.80 "volt and" E_(Cu,Cu^(2+))^(@)=-0.34 volt explain

Answer»


SOLUTION :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
