1.	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+)` ionsD. `cu^(-)` ion by the reduction of Cu
Answer» Correct Answer - C Since, `Ag^(+)` ions are reduced to Ag and `E_(Ag^(+)//Ag)^@ gt E_(cu^(++)//Cu)^@ Cu` is oxidized `Cu^(++)`.
