Zinc coating

Expert Answer:

Zinc is more reactive than iron and so will always oxidise before iron. Even if the zinc is just in a large block and iron is fully exposed, it will still oxidise first. To be oxidised, a metal must lose electrons. Zinc, being more reactive gives up electrons easier than iron.
