Hi!

A first-year student had two carbon electrodes, a KNO₃ saltbridge, one solution of ZnCl₂, and another solution of CuSO₄ on the other side. According to the student, there was a "precipitate" in the beaker with the CuSO₄ solution.

Nevermind that the first-year doesn't have the faintest clue what he's doing. Let's hope his observation was correct. But what should happen given this scenario, and why?
