the metal on which electroplating is to be done is taken as
cathode ( negative electrode) . the metal of which electroplating
is to be done is taken as anode ( positive electrode) and the salt
solution of the metal of which electroplating is to be done is
taken as electrolyte .
example-
if we want to electroplate iron with copper then iron is taken
as cathode and copper is taken as anode and electrolyte is copper
sulphate.Electroplating is the process of plating one metal onto
another by hydrolysis, most commonly for decorative purposes. This
is done through the use of copper in a copper sulfate bath.
