Take silver nitrate in a test tube and add pieces of copper in it and keep it undisturbed.
 
After some time the solution turns bluish and silver metal is precipitate at the bottom of the test tube.

Copper displaces silver from its salt solution to form copper sulphate. This is happened because the copper is more reactive than silver.
