This is a classic example of a single replacement chemical reaction, wherein copper ions precipitate out from solution onto the iron rod as iron atoms leave the rod and enter solution.

The blue color of the liquid is due to the copper ions in solution. You’ll notice that as the reaction proceeds and the copper precipitates out, the solution loses it’s blue color. The iron atoms in the rod give up their electrons to the copper ions in solution, so that the iron becomes oxidized while the copper becomes reduced."
