A site in electrolysis where metal goes into solution as a cation leaving behind an equivalent of electrons to be transferred to an opposite electrode called a cathode. Anodes routinely possess positive voltage and are responsible for eroding metal from electrodes through chemically oxidizing anions. Since anodes detail a plate that contains extremely high positive charges, anions will be attracted to it, which aids the oxidation process. What ends up resulting is reliant on the ionic substance, and ultimately leads to a non-metal matter or gas. Examples of these substances are oxygen, chlorine, iodine, and bromine.
Anodes arise from different sorts of metals such as magnesium, aluminum, and zinc which all have benefits in specific water sources. Aluminum anodes perform to the fullest within seawater, brackish and freshwater giving them the moniker as the best all-around anodes.
