Look at the before and after pictures for zinc and copper. Record macroscopic observations: what would you see if this experiment took place in front of you? Microscopic observations: what’s happening to the electrons and atoms? Record inferences for both silver and copper: oxidation or reduction? Anode or cathode?, half-reactions?
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.

In a redox reaction, the loss of electrons from a neutral atom is termed oxidation while the gain of electrons is called reduction. In an electrochemical cell, the oxidation process occurs at anode while reduction occurs at cathode.
