The zinc coating is in close contact with the iron to be protected, as well as with the moisture that would otherwise rust the iron. This makes it possible for ions and currents to flow through the system. As a result, because the zinc is consumed in preference to the iron as it is a more ready donor or electrons to the system. The zinc is said to act as a 'galvanic anode'.
Eventually the zinc will be consumed, as will the iron.

Zinc prevents iron from rusting through a process called galvanization. When zinc is applied to the surface of iron, it acts as a protective barrier against water and oxygen, preventing them from coming into contact with the iron. This barrier effectively stops the corrosion process, preserving the iron and preventing rust from forming.

Which metal prevent the rusting of iron?
zinc prevents rusting of iron by the process galvanisation
What element are nails coated with to prevent rusting?
Usually zinc because itis low cost, easy to cover the iron with, and prevents rusting
Is zinc is plated on iron?
to prevent rusting of the iron
What is the definition of the word galvanize?
To galvanize means that one is applying a protective layer of zinc on top of a product made of steel or iron. This prevents the steel or iron from rusting.
Can zinc prevent rusting of iron?
It decreases rusting but doesn't totally prevent it.
How does coating iron prevent rusting?
Coating prevent the iron from contacting air and moisture. So it prevents iron from rusting.
How does galvanise prevent rusting?
The process of depositing a layer of zinc over iron from preventing it to rust is called galvanisation. Galvanisation does not let iron come in contact with oxygen so it does not allow it to rust and corrode. Since, iron does not come in contact with oxygen it doesn't react.
What cause zinc to rust?
Zinc doesn't rust; zinc protect iron (and alloys) from rusting.
Does galvanizing iron involve covering it with a thin layer of zinc?
Yes, the zinc layer helps to preserve the iron sheet from rusting.
Which metals can be used to protect iron from rusting and how?
Try covering it in Zinc
Iron can be galvanised by coating it with zinc this can protect the iron by stopping it from rusting?
Zinc has a greater resistance to corrosion than iron does, however it will still eventually corrode away, leaving the iron surface exposed. Its main purpose is to prolong the resistance of iron by rusting instead of it.
How do painting prevent rusting?
Prevents contact of Iron with oxygen and water
