When copper metal reacts with silver nitrate solution, a single - displacement reaction occurs. Copper displaces silver from silver nitrate, forming copper nitrate and silver metal. Silver metal is a solid that comes out of the solution, and silver nitrate was colorless initially. Copper metal is not in solution. Copper nitrate in solution is known to have a blue color.
