(a) Name a metal which does not stick to glass?(b) Name a non-metal which is good conductor of electricity?(c) Name the metal which is commonly used in thermit welding?(d) What gets deposited at the cathode, a pure or impure metal?(e) What is the nature of Zinc oxide?
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.
