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.
Galvanizing protects in two ways: 1  It forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal. 2  The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.alvanizing protects in two ways: 1  It forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal. 2  The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
