In both galvanic and electrolytic cells, which process always occurs at the anode?
Answer and explanation
Correct answer: C. Oxidation, in which species lose electrons to the electrode surface
- Step 1: Anode is defined as the electrode where oxidation takes place. Step 2. The polarity differs between cell types but the process does not. Answer: oxidation. Why not the others: reduction is at the cathode, neutralisation is not an electrode process, and metal deposition is a reduction.
