# In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.

The 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.
This is a Displacement reaction as copper is more active than Silver(referring to activity series),copper displaces silver from its nitrate solution.
