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
In an electrochemical cell, the direction which electrons travel is: (a) from the anode to the cathode through the external circuit.
Electrons can be defined as the subatomic particles of a chemical element that are negatively charged and have a magnitude of -1.
An electrochemical cell refers to a device that is capable of either generating electric current from the electrical energy released by a spontaneous redox reaction or using an electrical energy to cause chemical reactions.
Generally, an electrochemical cell is also referred to as a secondary cell and a good example is a rechargeable battery.
In Science, the direction of flow of current is usually from the anode (positive side) to the cathode (negative side) in an electrical circuit.
On a related, current is made up of electrons and as such the direction which electrons travel is usually from the anode to the cathode through the external electrical circuit.
