A voltaic cell was constructed using a zinc electrode (submerged in zinc sulfate), a copper electrode (submerged in copper(II) sulfate), and a salt bridge containing sodium sulfate. Given that zinc more easily forms cations than copper, which of the following statements is true concerning this voltaic cell? a. Electrons flow from the zinc anode to the copper cathode.
b. The mass of the anode increases over time.
c. Sulfate ions from the salt bridge will migrate to the zinc sulfate solution.
d. Sodium ions from the salt bridge will migrate to the copper sulfate solution.
