Question

in refining of silver , silver is obtained from silver nitrate solution by copper metal by ............... process​

Answer 1

Answer:

silver nitrate is in solution and the metallic copper will dissolve to form copper nitrate; as it does, it will precipitate the silver in solution as metallic silver. That is, copper is exchanged for the silver in solution and silver is replaced by the copper that is not in solution

Answer 2

In the refining of silver, silver is obtained from silver nitrate solution by copper metal by displacement process

• In the solution of silver nitrate, the metallic copper dissolves to form copper nitrate.

• It precipitates the silver in solution as metallic silver.

• In other words, copper is exchanged for the silver in the silver nitrate solution.

• On the other hand, silver is replaced by the copper that is not present in the solution.

• Therefore, copper displaces silver because it is more reactive than silver.

• The chemical reaction involved in this displacement process is :

         2AgNO₃ + Cu → 2Ag + CuNO3₂
