“3.I think that chlorine gas appears at one electrode as copper appears at the other electrode.”

1.“I think the copper appears at one electrode because it is a metal and magnetic.”

2.“I don’t think that any electrons areinvolved in this process.”

“6.Chlorine is a non-metal and covalent and thereforedoes not conduct electricity.”

“4.Copper is formed at the anode (+) and is therefore positive.” Copper Chloride Solution

“5.Cl2 bubbles appear at the anode andSo Cl2 must be negative.”

“9.Copper ion needs electrons to form copper metalat the cathode (-).”

7.“Copper is a metal and forms ionic compounds. Copper chloride is therefore an ion and conducts electricity”
