Question

Galvanising means coating an iron (Fe) or steel object with a layer of zinc (Zn) to protect it from

corrosion. Steel cans can also be coated with tin (Sn), also to protect it from corrosion, including

fruit juices in 'tin' cans. When the zinc coating is scratched through to the iron underneath, the iron

still does not corrode initially. However, if the tin surface is scratched through to the iron, the iron

corrodes even faster compared to when there was no coating at. This means?

A. Iron corrodes slower when connected to a less reactive metal

B. Zinc is less reactive than iron

C. Iron corrodes faster when connected to a more reactive metal

D. Tin is less reactive than iron
