A hypothetical metal ( M ) forms coating of Sn when placed in SnCl2 solution. When a strip of Ni is placed in MCl2 solution a coating of M forms on the nickel surface. a) Compare the strengths of Ni , Sn and M as an oxidizing agent. ____ _____ ____ Strongest ox ag weakest ox ag Predict which pair will give a reaction , Ni + Sn+2 or Sn + Ni+2 (explain very shortly )
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.
