Chemical reactions and equations

Question:

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

Answer:

Displacement reaction: Displacement reaction is the type of reaction in which the reactive metal displaces less reactive metal in the solution. The copper is more reactive metal than silver. So, copper will displace silver from the solution to form copper nitrate.

2AgNO3 (aq) + Cu (s) → Cu(NO3)2 (aq) + 2Ag (s)
