When a copper wire is placed I a solution of `AgNO_3`, the solution acquires blue colour. This due to the formation of .

A

Soluble complex of copper with `AgNO_3`

B

`Cu^(+) ions`

C

`Cu^(2+)` ions

D

`cu^(-)` ion by the reduction of Cu

Text Solution

Verified by Experts

The correct Answer is:
C
Since, `Ag^(+)` ions are reduced to Ag and
`E_(Ag^(+)//Ag)^@ gt E_(cu^(++)//Cu)^@ Cu` is oxidized `Cu^(++)`.
