What is the driving force for corrosion of metals? Provide a brief description. Correct Answer-The metals want to constantly be at their lowest energy state and will do whatever they can to make that happen. When it does, corrosion is created. Which of the following defines the oxidation and reduction reactions happening in corrosion reactions? Correct Answer-Reduction happens when metals receive electrons and oxidation happens when metals lose electrons. According to following galvanic se...
