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… Witryna27 gru 2024 · The underground brine in non-oxidizing state is an underground brine having no oxidative property, and usually has an oxidation-reduction potential of 0 mV or less, preferably 0 to −50 mV as a platinum electrode potential.
