In a galvanic cell, electrons flow from anode to cathode through
Correct answer: D. all of the above
- A. external electric circuit
- B. salt bridge
- C. movement of ions
- D. all of the above
Explanation
The flow of electrons occurs through a complete circuit:(a) Electrons move through the external wire connecting anode and cathode.(b) Ions flow through the salt bridge, balancing the charge transfer.(c) Ionic movement within the electrolyte also contributes to the current flow.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
