What will happen if a piece of silver metal is placed in a solution of zinc nitrate?

Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate.

Explanation:

This single replacement reaction will produce silver metal, Ag , and aqueous zinc nitrate, Zn(NO3)2 . Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate. Notice that this is also a redox reaction.
