Question

In an electrochemical cell, electrons travel in which direction? * (a) from the anode to the cathode through the external circuit (b) from the anode to the cathode through the porous cup (c) from the cathode to the anode through the external circuit (d) from the cathode to the anode through the porous cup.

Answer 1

Answer:

(a) from the anode to the cathode through the external circuit

Explanation:

In an electrochemical cell, there are two half cells; the oxidation half cell and reduction half cell. Oxidation typically refers to loss of electrons and reduction refers to gain of electrons.

Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell.

The electrical circuit in an electrochemical cell confirms the flow of electron. Usually a light bulb is attached. The correct option is;

(a) from the anode to the cathode through the external circuit
