Write the equations involved in electrochemical reaction of corrosion. B. Give 1 example each for electrorefining and electroplating, describe the reaction/process and draw a simple diagram including (a) anode and cathode, (b) direction of electron flow, and (c) movement of cations and anions. Electrorefining and electroplating are commonly used in some commercial electrolytic processes. Electrorefining is the purification of metals by means of electrolysis while electroplating is the coating of one on the surface of another using electrolysis. Electrorefining Process Diagram 2.

Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
