You know that a brand-new bicycle has shiny handlebar and wheel rims. However, if these are accidentally scratched, the shiny coating comes off revealing a not so shiny surface beneath. Which of the following method is used for depositing shiny layer?

Electroplating method

The correct answer is option 2. Electroplating method.

The process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.

It is one of the most common applications of chemical effects of electric current.

For example, chromium plating is done on many objects such as car parts, bath taps, kitchen gas burners, bicycle handlebars, wheel rims, and many others.
