)Assertion: Corrosion is a beneficial process for metals. Reason : Galvanising and electroplating of metals prevent corrosion.
mylen [45]
The assertion is definitely wrong. Corrosion actually means decomposing or rusting of metals. So, corrosion is a harmful process for metals. But, your reason is correct. Galvanising, which means deposition of a layer of zinc on iron to prevent from rusting, is a very beneficial process to prevent metals from corrosion. In some cases, electroplating also helps to prevent from corrosion.

Hope it helps
