Revision notes on Electroplating for the Cambridge (CIE) IGCSE Chemistry syllabus, written by the Chemistry experts at Save My Exams.
• Electroplating is the plating of one metal on the top of the other. • The object to be plated is made the cathode. • The metal that is used to plate the object is made the anode.
Explain how the process of electroplating works Similar setup to electrolysis: The metal being coated is the cathode. The metal that will form the exterior layer is the anode. The electrolyte solution must contain ions of the metal which will form the outer coating. A power supply is connected to both electrodes. https:bit.lypm t-cc https:bit ...

CHEMISTRY 12 – ELECTROPLATING & METAL REFINING WORKSHEET. 1) Consider the following diagram: A copper spoon is plated with silver in an electrolytic cell. (a) What is the reaction at the anode? (1 mark) Ag → Ag+ + e- (b) What is the reaction at the cathode? (1 mark) Ag+ + e- → Ag.
What is electroplating? Electroplating is a process where the surface of one metal is coated with a layer of a different metal. The anode is made from the pure metal you want to coat your object with. The cathode is the object to be electroplated. The electrolyte is an aqueous solution of a soluble salt of the pure metal at the anode
Set-up for electroplating with silver. 11 Aqueous copper(II) sulfate solution is electrolysed using inert electrodes. Copper( II) ions (Cu2+), hydrogen ions (H+), hydroxide ions (OH–) and sulfate ions ( ) are SO 4 present in the solution.
