Anode and Cathode: Definition, Differences, Charges and

WitrynaH+ ions are attracted to the cathode, gain electrons. and form hydrogen gas; OH-ions are attracted to the anode, lose electrons and form oxygen gas; The overall balanced equation. for the process is: Reducing agents and oxidizing agents are the ones responsible for corrosion, which is the "degradation of metals as a result of electrochemical activity". Corrosion requires an anode and cathode to take place. The anode is an element that loses electrons (reducing agent), thus oxidation always occurs in the anode, and the cathode is an element that gains electrons (oxidizing agent), thus reduction always occurs in the cathode. Corrosion occurs whenever ther… derby wa weather forecast https://floriomotori.com
