Answer 2

Explanation:

The reaction taking place when a copper coin is placed in silver nitrate solution is a Displacement reaction.

Explanation:

Copper is more reactive than silver. Hence, displacement reaction occurs. When copper coin is dipped in silver nitrate solution, it forms copper nitrate and silver metal. ... The grey solid crystal(glitters) of Ag metal appears on the copper coin and solution turns blue in colour.
