The Role of the Cathode in a Galvanic Cell

Galvanic cells: the role of the Cathode

Galvanic cells are devices that use the spontaneous redox energy to generate electricity. To make a galvanic device work correctly, it is necessary that both half-reactions of oxidation or reduction occur at the correct place. Both the anode and cathodes are responsible for the half-reactions of oxidation and reduction. The movement of electrons between the anode and the cathode facilitates this process. This electron flow can be facilitated by the use of an electrolyte and a salt bridge within a galvanic cell (Lubin 2019). There are many reasons why the cathode matters. It is where the electrons from the anode are transferred to the cathode, which then produces the electricity. The anode accepts electrons and reduces the atoms. This causes electrons to flow from anode into cathode creating electrical current. The cathode also allows electrons to flow. This is called the external circuit, and it is vital for galvanic cells. A galvanic cell’s cathode, which is an integral component, plays a crucial role in the generation of…
