Explanation:
Copper is more reactive than silver.
When copper reacts with AgNO3, Cu displaces Ag from AgNO3, forming Cu(NO3)2.
Chemical reaction -
[tex]Cu + 2AgNO_3 = 2Ag + Cu(NO3)_2[/tex]
It's a displacement reaction as well as redox reaction.
Reasons are :
The Oxidation number of Cu changes from 0 to 2 so it's oxidized.
Oxidation number of Ag changes from 1 to 0 so it's reduced.
So, it's also a redox reaction.
