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.

anode cathode reduction oxidation

e⁻ → e⁻ →

zn⁻ cu⁺
salt bridge
electrode electrode

zn²⁺ cu²⁺

process process

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 half - cell: Zinc (Zn) is losing electrons to form \(Zn^{2+}\) (reaction: \(Zn
ightarrow Zn^{2 +}+2e^-\)), so this is the anode and the process is oxidation. For the Cu half - cell: Copper ions (\(Cu^{2+}\)) are gaining electrons to form Cu (reaction: \(Cu^{2+}+2e^-
ightarrow Cu\)), so this is the cathode and the process is reduction. Also, the direction of electron flow is from the anode (Zn) to the cathode (Cu), which matches the given electron flow arrows (\(e^-\) moving from Zn to Cu through the wire).

Answer:

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