Question

drag each label to the correct location on the image. label each half cell in this diagram of a voltaic cell to identify which electrode it contains and the process occurring at the electrode.

Explanation:

In a voltaic cell, the anode is where oxidation occurs (loss of electrons), and the cathode is where reduction occurs (gain of electrons). For the Zn electrode: Zn is losing electrons to form \( Zn^{2+} \) (oxidation), so the Zn electrode is the anode. For the Cu electrode: \( Cu^{2+} \) is gaining electrons to form Cu (reduction), so the Cu electrode is the cathode. Electrons flow from anode (Zn) to cathode (Cu).

• Left electrode (Zn): anode (electrode), oxidation (process)
• Right electrode (Cu): cathode (electrode), reduction (process)

Answer:

• Left "electrode" box: anode
• Left "process" box: oxidation
• Right "electrode" box: cathode
• Right "process" box: reduction
