Nonspontaneous Redox: Electrolysis and Electroplating

In an electrolytic cell, the positive electrode is the

• anode, where oxidation occurs
• anode where reduction occurs
• cathode where oxidation occurs
• cathode where reduction occurs

What occurs during electrolysis of a molten salt?

• Electricity is produced by a spontaneous redox reaction
• Electricity cause a non-spontaneous redox reaction to occur
• Electrons flow through the molten salt
• Electrons are removed from both ions of the molten salt
