Question

During reconstruction of the Statue of Liberty, Teflon spacers were placed between the iron skeleton and the copper plates that cover the statue. What purpose do these spacers serve?

Short answer

These spacers keep the copper and iron metals apart and prevent the iron from corroding.

Step-by-step solution

Use of Spacers

These spacers separate the copper and iron metal. prevention of contact stops the electron from transferring from one metal to another, it prevents reduction and oxidation to occur.

This prevents corrosion of the iron metal.

Hence these spacers separate the copper and iron metals and prevent corrosion of the iron metal.
