उत्तर
The electroplating of an article with nickel requires an electrolyte which must be a solution containing nickel ions. The article to be plated is placed as the cathode of the cell in which the plating is carried out. The anode of the cell is made from pure nickel. The ions that are attracted to the negative electrode and discharged are called cations.
