Definition - What does Anodic Reaction mean?
An anodic reaction is a type of reaction that occurs in an electrochemical cell. More specifically, it is a half reaction, with the other half reaction in an electrochemical cell being a cathodic reaction. Anodic reactions involve the flow of electrons from the anode, and can cause corrosion to occur.
Corrosionpedia explains Anodic Reaction
Anodic reactions are reactions that occur in an electrochemical cell at the anode, which is the positive electrode in the electrochemical cell. The anode is positively charged because electrons are flowing from it. The cathode, or the negative electrode, receives electrons in the electrochemical cell. Electrons flow off of the anode and into an electrolytic solution. During this process, the cathode receives electrons via the electrolytic solution.
When electrons flow off of the anode it is known as oxidation. When electrons combine with the cathode, it is known as reduction. Anodic and cathodic reactions can cause corrosion to occur.
