A spoon to be electroplated with gold should be

Options

  1. Acathode
  2. Banode
  3. Celectrolyte
  4. Dnone of these.

Correct answer

A. cathode

Step-by-step solution

Standard electrode potential for Gold is Au ³⁺+3 e⁻ Au is 1.50 volt. therefore, gold get easily reduced. So to electroplate gold on the spoon, spoon should be made cathode as reduction takes place on cathode.
