Question

which electrode do the copper ions move towards

Answer 1

for example Copper sulfate, CuSO4 ===> (Cu^2+) (SO4^2-).
That means copper ions have a positive charge in the solution of this compound and are therefore attracted to the negative electrode, cathode. Just wanted to clear that out because "it accepts electrons there" is an invalid and ambiguous answer.
Good luck.

Answer 2

What is the other electrode?
