although zinc is more reactive than iron but still we use zinc for the galvanization of iron - Science - Chemical Reactions and Equations

Question

although zinc is more reactive than iron but still we use zinc
for the galvanization of iron ??
acc to the activity series of metals zinc is more reactive than
iron so instead of preventing iron from rusting zinc would have
reacted more but it is not like this why?

Arti Gujrati · Accepted Answer

Zinc metal is generally used for protecting
iron and the process is called galvanization In this method,
surface of iron is covered with layer of more active metal like
zinc Being more reactive Zinc metal loses electrons (undergoes
oxidation) first in compare to iron and hence,iron remains
unreactive towards atmospheric oxygen and moisture This prevents
the rusting of iron
