Two half cells of a galvanic cell are connected with a salt bridge, the electrons flow from:
Correct answer: A. Anode to cathode through external circuit
- A. Anode to cathode through external circuit
- B. Cathode to anode through external circuit
- C. Anode to cathode through salt bridge
- D. Cathode to anode through salt bridge
Explanation
In a galvanic cell, the anode is where oxidation occurs (loss of electrons), and the cathode is where reduction occurs (gain of electrons). The electrons flow from the anode to the cathode through the external circuit, creating an electric current. The salt bridge is used to maintain electrical neutrality in the half-cells by allowing ions to flow between them.

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.
