Salt bridge transfers_______________?
Correct answer: D. ions
- A. electrons
- B. anion
- C. current
- D. ions
Explanation
A salt bridge contains an inert electrolyte whose cations and anions migrate to maintain electrical neutrality in the two half-cells, so it transfers ions rather than electrons. Electrons travel through the external wire. The likely wrong choice is current, because the salt bridge completes the internal ionic circuit but does not carry electronic current.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
