Final answer:
The 'Absence of moisture' is NOT a requirement for corrosion; moisture is essential as corrosion often involves metals reacting with oxygen and water.
Step-by-step explanation:
The condition that is NOT one of the requirements for corrosion to occur is 'Absence of moisture'. Corrosion is a galvanic and REDOX process where metals deteriorate through oxidation to their oxides. The presence of an electrolyte, oxygen, and a metal are necessary for corrosion to occur. For example, iron will rust when exposed to oxygen and water as a galvanic cell is created on the iron surface. Likewise, aluminum is safeguarded against corrosion by a thin coating of aluminum oxide that acts as a barrier. Therefore, moisture is crucial for the corrosion process, particularly for metals like iron that rust. Without moisture, such as when iron is immersed in an organic solvent like kerosene saturated with oxygen or deoxygenated water, corrosion doesn't occur.
