Iron rusting on the village ploughshare is best described as:
AA purely physical change at the iron surface in dry conditions
BAn electrochemical corrosion involving Fe, O$_2$, and water
CSublimation of iron oxide from the surface into the air
DA nuclear decay process of iron atoms on the metal surface
Answer & Solution
Correct answer: B. An electrochemical corrosion involving Fe, O$_2$, and water
Rust forms electrochemically: Fe oxidises in presence of O$_2$ and H$_2$O.
