Question

why does Cu released from Ag No3 solution.​

Answer 1

Answer:

Cu + 2AgNO3 → Cu(NO3)2+ 2Ag

From the given reaction the following things can be determined or indicated

The reaction is a redox reaction.

Both oxidation and reduction are taking place simultaneously. Copper is oxidised and silver is reduced.

Copper is more reactive than silver

Since copper displaces silver from silver nitrate solution, so copper is more reactive than silver. Cu is a reducing agent, AgNO3 is an oxidizing agent. When copper turnings are added to the silver nitrate solution, a blue-coloured solution is formed after some time.
