Q1: In connection with corrosion of metals, passivation is the process that

ANS:C - inhibits further deterioration.

Inhibiting further deterioration means that passivation prevents or slows down the process of corrosion on the surface of a metal. When a metal undergoes passivation, a protective oxide layer forms on its surface. This oxide layer acts as a barrier between the metal and the surrounding environment, effectively blocking the penetration of corrosive agents such as moisture, oxygen, and other chemicals. As a result, the metal is less susceptible to corrosion, and its degradation is slowed down or halted altogether. In this way, passivation helps to maintain the integrity and longevity of the metal, extending its useful lifespan and preventing further damage or deterioration.
