Question
Define ‘electroplating’. How can steel spoons be plated with silver? Explain with the help of a diagram.
Answer
The process of depositing a thin layer of some desired metal, over some other metallic object, with the help of an electric current is called electroplating.
For this, a plate of pure silver is made the anode, while the steel spoon is made the cathode. When electric current flows through the set-up, pure silver from anode dissociates and gets deposited on cathode. Thus, a coat of silver is applied on the spoon.
