Question

Chromium is a shiny metal that does not corrode. Instead of electroplating iron with chromium, why are sanitary fittings not made of chromium itself?

Answer 1

Chromium is very costly and is not economically friendly. That is why iron is electroplated with a thin layer of chromium to make it less corrosive rather than using chromium itself.It is also not an abundantly found element and is difficult to extract.
