Electroplating
- Electrolysis is used to electroplate objects
- For example, to cover a cheaper metal
with a more expensive one
- Like covering cheap jewellery with
gold for its aesthetic qualities
- How it works
- The negative electrode should be the one
that is to be electroplated
- i.e. cheap jewellery
- The positive electrode should be the material
you want to coat the object with
- i.e. gold
- The electrolyte should be a solution of the
coating metal, such as its metal nitrate or
sulphate
- i.e. Gold Nitrate
- For example, the cheap jewellery would act as the
negative electrode and the positive electrode would
be made of gold, in a electrolyte solution of gold
nitrate
