Question

State reason that iron articles loose their shine gradually.

Answer 1

It is astonishing to learn that iron articles in actual get coated in the layer of rust.

Gradually iron, due to reaction with moisture/oxygen results in the formation of rust. The rust we see is actually a reaction between iron and oxygen which leads to the formation of Iron Oxide.

What we see is actually Iron Oxide which leads to the eradication of Iron's shine
