Sir, what is the reason that iron does not get corroded even after zinc layer removed

[@Naturequr]

because zinc is more reactive than iron and hence can be easily oxidized. Thus when zinc layer breaks down, the zinc continues to react and get oxidized. Hence iron object is protected.

[@kamraneagle]

Why u heat it after zinc chloride it dry room temperature?
