A voltaic cell is set up, and a chemical reaction proceeds spontaneously. Which of the following will not occur in this reaction?
A. The electrons will migrate through the wire.
B. The cations in the salt bridge will migrate to the anode half-cell.
C. The cathode will gain mass.
D. The anode will lose mass.
E. Reduction will occur at the cathode.
Answer (2)
d. anode will lose mass because anode has negative charge and electrons loss by cathode will move to anode through a circuit to external wire
All the processes listed in the options (A-E) occur in a spontaneous reaction in a voltaic cell. Therefore, none of the options can be accurately described as not occurring. Hence, the answer to the question is that each described event indeed happens in such a cell.
