Answer 1

Answer:

Copper metal is more reactive than silver metal thus, when copper coin is kept immersed in silver nitrate solution for some time, it displaces silver from silver nitrate solution.

The reaction is :

Cu+2AgNO

→Cu(NO

+Ag

The grey solid crystal of Ag metal are seen growing on the copper coin and solution turns blue in colour.
