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

Displacement and double displacement reactions are two types of chemical reactions that involve the exchange of ions or atoms between reactants.
Displacement Reaction:

In a displacement reaction, one element displaces another element from a compound.
In the refining of silver, the recovery of silver from a silver nitrate solution involves a displacement reaction using copper metal. The reaction can be represented as follows:

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

In this reaction:

Silver nitrate (AgNO3) is an aqueous solution containing dissolved silver ions (Ag+) and nitrate ions (NO3-).
Copper metal (Cu) is added to the solution.
As a result of the displacement reaction, copper displaces silver from the silver nitrate solution.
Solid silver (Ag) is formed as a grayish-white precipitate or solid.
Copper nitrate (Cu(NO3)2) is formed in the solution.
This reaction is commonly used in the extraction and purification of silver from various silver-containing compounds or solutions. It allows for the conversion of soluble silver ions into solid silver, which can then be collected, separated, and further purified to obtain pure silver metal.
