Which of the following take place during cathodic protection? A. The sacrificial metal oxidizes more readily than the protected metal. B. The sacrificial metal reacts spontaneously with the protected metal. C. The sacrificial metal act as the cathode. D. The sacrificial metals accept electrons from the protected metal
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.
