When an iron object is plated with tin, tin does not act as sacrificial anode in protecting against corrosion, because.

Options

  1. Atin is more reactive than iron
  2. Btin is less reactive than iron
  3. Creactivity of tin and iron is same
  4. Dtin is oxidising agent while iron is not so

Correct answer

B. tin is less reactive than iron

Step-by-step solution

Because tin is less reactive than iron, so when an iron object is plated with tin, it does not act as sacrificial anode in protecting against corrosion.
