In an electrolytic cell, oxidation takes place at the
Answer and explanation
Correct answer: C. anode
- Step 1: Electrochemical and electrolytic cells involve coupled oxidation-reduction half-reactions occurring at distinct electrode surfaces.
- Step 2: By universal electrochemical convention, oxidation (loss of electrons) always occurs at the anode, whereas reduction (gain of electrons) occurs at the cathode.
- Step 3: In an electrolytic cell driven by an external power source, the anode is the positive electrode where anions migrate and lose electrons.
Answer
anode.
Why not the others: electrolyte is the ionic conducting medium in which electrodes are immersed; salt bridge maintains electrical neutrality between half-cells in a galvanic cell; cathode is the electrode where reduction (gain of electrons) takes place.
