When a copper wire is placed in a solution of AgNO_(3), the solution acquirs blue colour. This is due to the formation of

Answer»

`Cu^(2+)` ions
`Cu^(+)` ions
Soluble complexof copper with `AgNO_(3)`
`Cu^(-)` ION by the reduction of Cu

Solution :Since, `AG^(+)` ions are reduced to Ag and
`E_(Ag^(+)//Ag)^(o) gt E_(Cu^(++)//Cu)^(o)` Cu is oxidised to `Cu^(++)`.
