    Can someone please show me how I'd go about answering this table, please? I already have the formula column done, but i'm just stuck on the equations for the negative and positive electrode. I think I know how to answer the product formed at each electrode.

    Thanks in advance!!

    These are all molten substances, so the elements are liberated at the electrodes. Positive ions go to the negative electrode and vice versa.

    Thanks for the reply

    What do you mean by the elements are liberated? can you possibly show an example?

    Thanks in advance!!!!!!

    Copper ions have a 2+ charge and will migrate to the cathode (negative in electrolysis)

    When they get there they can pick up 2 electrons per ion to become copper atoms (the element).

    Cu2+ + 2e --> Cu
