Electroplating is used in _______________.
Q) Instead of taking the trouble of electroplating metals with chromium for making car parts , taps , cycle parts , etc., why are these objects not made up of chromium itself ?
A) This is because chromium is a very expensive metals . It is a metal which does not rust is resistant from scratches and has a shiny appearance . If we use chromium it will be a huge loss and it also be wastage of the resource chromium thus it is preferable to use chromium only for electroplating objects.
Could you please check my answer and give inputs.
The process of purification of an impure metal is like : (a) electroplating a metal on the same type of metal (b) electroplating a metal on another type of metal (c) producing a chemical compound by electrolysis (d) decomposing a chemical compound by electrolysis.
