A positive cell potential indicates a spontaneous galvanic cell reaction.
Consider the following cell:
Pb / Pb(NO₃)₂ (1.0 M) || AgNO₃ (1.0 M) / Ag
As this cell operates, which reaction occurs at the negative electrode?
✅ Correct Answer: B
Pb → Pb²⁺ + 2e⁻
Key concepts tested:
• Identifying the anode and cathode in a galvanic cell
• Oxidation vs. reduction reactions
• Electron flow in electrochemical cells
• Determining the negative electrode in a spontaneous cell reaction
Understanding galvanic cells is essential for success on the DAT General Chemistry section.
Think you know the answer?
A positive cell potential means the reaction is spontaneous.
Which electrode is negative in a galvanic cell, and what reaction occurs there?
Remember:
• Oxidation occurs at the anode
• Reduction occurs at the cathode
• In a galvanic cell, the anode is negative
Take a moment to work through it before revealing the solution on the next slide.
