Water is the most abundant nutrient in our body and plays an important transmission function in every body cell and tissue. Sixty percent of our body weight is water. The fact that you can live without food for a long period of time, even months, but live only for a few days without water is true.
The addition of zinc, a sacrificial anode, would prevent the iron metal from corroding. According to the table of Standard Reduction Potentials, the standard reduction potential of zinc is about -0.76 volts. The standard reduction potential of iron is about -0.44 volts.
Rust is then quickly produced by the oxidation of the precipitate. The rusting of unprotected iron in the presence of air and water is then inevitable because it is driven by an electrochemical process. However, other electrochemical processes can offer some protection against corrosion.
