Properties of Pure Iron
| Property | Description |
|---|---|
| Color | Dark silvery-gray |
| Texture | Soft |
| Luster | Lustrous |
| Reactivity | Highly reactive, especially with acids, air, and water. |
| Common Reaction | Forms oxides (rust) when exposed to air and water. |
Why is Pure Iron Dark Silvery-Gray?
- The metallic bonding in iron allows electrons to move freely, resulting in its characteristic luster.
- The specific electron arrangement absorbs and reflects light in a way that appears dark silvery-gray to our eyes.
Practical Aspects of Iron's Color:
- Appearance: In its pure, freshly prepared state, iron has a characteristic silvery-gray appearance.
- Rusting: When exposed to the environment, the surface of iron reacts with oxygen and water, forming reddish-brown iron oxides (rust), which is very different from its pure color.
In summary, while often associated with the reddish-brown color of rust, pure iron is a dark silvery-gray metal.
