C3H8O2 (a) + Cr2O72– (aq) → C3H4O4 (aq) + Cr3+ (aq) Identify the element oxidized and the number of electrons that must be included in the unbalanced oxidation half-reaction. Then Identify the element reduced and the number of electrons that must be included in the unbalanced reduction half-reaction.
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.
