6 FAQs about [Battery anode participates in the reaction]
What is the role of an anode and cathode in a battery?
The anode and cathode, known as the battery’s electrodes, play crucial roles. The anode (negative electrode) discharges electrons into the external circuit, while the cathode (positive electrode) accepts these electrons. In the middle, the electrolyte acts as a medium, facilitating the flow of ions.
How does a cathode react with an anode?
At the same time, the cathode goes through a reduction reaction in which the cathode substance, ions and free electrons also combine to form compounds. While this action may sound complicated, it's actually very simple: The reaction in the anode creates electrons, and the reaction in the cathode absorbs them. The net product is electricity.
What happens in an anode oxidation reaction?
The anode experiences an oxidation reaction in which two or more ions (electrically charged atoms or molecules) from the electrolyte combine with the anode, producing a compound and releasing one or more electrons.
