ОА, А

Answer 1

C.cathode, cathode

Step-by-step explanation:

In electrolysis, a device called ELECTRODE, which electric current passes through is used. However, electrodes can either be anode or cathode depending on the charge. Anode is a positive electrode that attracts negative ions while cathode is a negative electrode that attracts positive ions.

According to this question, Copper (Cu) and hydrogen (H) which are both positive ions i.e. Cu2+ and H+ will move towards and form at the CATHODE. Hence, the answer is cathode, cathode for the respective element.
