What is the purpose of providing a sacrificial electrode of another metal during corrosion prevention?

Options

  1. ATo increase the cost of corrosion prevention.
  2. BTo improve the appearance of the metal.
  3. CTo corrode the object faster.
  4. DTo save the object from corrosion.

Correct answer

D. To save the object from corrosion.

Step-by-step solution

An electrochemical method is to provide a sacrificial electrode of another metal (like Mg, Zn, etc.) which corrodes itself but saves the object.
