The answer should be 4. All of the above.
Answer:
Co(s)→Co3+(aq)+3e−
Explanation:
The half-cell reaction may be defied as the reaction taking place at an individual anode or cathode. The oxidation and reduction reactions occur at the electrodes.
Oxidation reaction occur at anode and reduction reaction at cathode. The half-cell reaction for cobalt silver voltaic cell, the oxidation of cobalt occurs at anode. The cobalt loses its 3 electrons and converted to aqueous state from the solid state.
Thus, the reaction at anode is Co(s)→Co3+(aq)+3e− .
