Question

What is electroplating done ? Give two reasons.

Answer 1

Electroplating is a process of applying a layer of non-corrosive alloy on a normal metallic surface through the chemical process of electrolysis.

It is done for the following reasons -

• First of all, the electroplating provides our non corrosive layer of alloy on the metal surface. This increases the lifespan of the metal surface and prevents the unwanted surface corrosion.
• Secondly, the electroplating of shining alloys like chromium, gives the metallic surface a beautiful finish for the sake of good aesthetics of a finished product.
• The electroplating is also used to produce cheap costume jewellery with the extremely thin platings of gold and silver.
