Electroplating Quiz

What is Electroplating?

• A process of coating an object with a layer of metal using an electric current

• A process of removing the metal layer from an object using an electric current
• A process of coating an object with a layer of metal using extreme heat

• Anode-Positive

  Cathode-Negative

• Anion-Negative

  Cation-Positive

Assertion-The neutral atoms eventually of the metal get deposited on the surface of the cathode.

Reason-When electric currant is passed through the setup, the cations of the metal from the salt solution move towards the cathode and get neutralized by the electron present there.
