An aqueous solution of copper(II) sulfate (CuSO4\text{CuSO}_4CuSO4) is electrolysed using inert carbon electrodes as shown in the diagram below.
Which ions are attracted to the positive electrode (anode) during this process?
Cu2+\text{Cu}^{2+}Cu2+ and H+\text{H}^+H+ ions
SO42−\text{SO}_4^{2-}SO42− ions only
SO42−\text{SO}_4^{2-}SO42− and OH−\text{OH}^-OH− ions
Cu2+\text{Cu}^{2+}Cu2+ and SO42−\text{SO}_4^{2-}SO42− ions
