At which electrode does oxidation occur in a galvanic cell?
Answer and explanation
Correct answer: C. The anode
- Step 1: Oxidation is loss of electrons and always takes place at the anode. Step 2. In a galvanic cell the anode is the negative electrode. Answer: the anode. Why not the others: reduction takes place at the cathode, and the salt bridge only keeps charge balanced.
