Consider the following voltaic cell, which utilizes a salt bridge containing K+ and NO3–: Zn (s) ∣ Zn2+(aq) ‖ Cd2+(aq) ∣ Cd (s) Identify the anode and cathode, and indicate the direction of potassium ion and nitrate ion flow from the salt bridge. Group of answer choices: Cd is the anode and Zn is the cathode; NO3– flows into the anodic cell and K+ flows into the cathodic cell. Actually, it is the Zn2+ and Cd2+ ions that move into the salt bridge. Cd is the anode and Zn is the cathode; K+ flows into the anodic cell and NO3– flows into the cathodic cell. Zn is the anode and Cd is the cathode; K+ flows into the anodic cell and NO3– flows into the cathodic cell. Zn is the anode and Cd is the cathode; NO3– flows into the anodic cell and K+ flows into the cathodic cell.
