Interpretation Introduction

Interpretation:

1. Formation of rust in old cars
2. Conditions that lead to rust formation

Concept Introduction:

Rust is an iron oxide. It is generally a red oxide formed by the redox reaction of iron and oxygen in the presence of air moisture or water. There are various kinds of rust that areevident both visually and by spectroscopy, and are formed under dissimilar circumstances. Rust consists of hydrated iron(III) oxides Fe₂O₃.nH2O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)₃).
