An experiment to show how electroplating using copper electrodes. Aim To find the amount copper gains or loses on the electrodes using different amounts of current each time during electrolysis. How the changing of current affects the electroplating of copper. Introduction Electroplating is generally carried out in order to improve the appearance or corrosion resistance of the surface of a metal by electrodepositing a thin layer of metal ion on it. The metal substrate to be coated is made by the cathode in an electrolytic cell. The cell used in electroplating contains an electrolyte which is usually an aqueous solution containing a reasonably high concentration of an ion of the metal which is to be electroplated on the surface. The cell anode is usually a piece of the metal to be plated from solution; this enables the anode reaction of metal dissolution to replace the metal ion lost from solution by the cathodic decomposition. Factors There...
