Question

reactivity on metals how it help in electroplating and galvanizing process

Answer 1

Reactivity of metals is imported if you want to protect the metal by the process of GALVANISATION and ELECTROPLATING..........

It is because you should apply the coating of more reactive metal to the metal which you want to protect......so for doing it you must know the series of reactivity of metals for choosing an appropriate one........

Answer 2

Answer:

Galvanising is a method of rust prevention. The iron or steel object is coated in a thin layer of zinc. This stops oxygen and water reaching the metal underneath - but the zinc also acts as a sacrificial metal . Zinc is more reactive than iron, so it oxidises in preference to the iron object.
