When a copper wire was left in silver nitrate solution for sometime, it was observed that the solution turned bluish green.
(i) Explain the observation .
(ii) Write the balanced chemical equation to represent the change taking place.

Text Solution

Verified by Experts

(i) Copper is more reactive than silver. Hence, when copper wire is dipped in silver nitrate solution, it displaces silver from `AgNO_(3)` solution forming copper nitrate which is blush green in colour.
(ii) `Cu+2AgNO_(3)rarrunderset(("Copper (II)nitrate bluish green"))(Cu(O_(3))_(2))+underset(("Silver"))(2Ag)`
