In a galvanic cell, which statement about the anode is correct?
Answer and explanation
Correct answer: B. Oxidation occurs there, and it is the negative electrode
- Step 1: The anode is where oxidation occurs (the mnemonic is AN OX).
- Step 2: In a galvanic cell the anode releases electrons into the external circuit, so it is the negative terminal.
Answer
oxidation; negative electrode.
Why not the others: The other options pair reduction with the anode or give the wrong charge.
