A solution of iodine (I₂) in water typically displays a light orange-brown color.
Understanding Iodine's Appearance
While iodine in its pure forms exhibits different appearances, its interaction with water results in a distinct color. When dissolved in water, iodine forms an aqueous solution that is characterized by its light orange-brown hue. This coloration is a key indicator when working with iodine solutions in various chemical contexts.
To provide a comprehensive view, here's how iodine appears in its different states:
| Form of Iodine | Typical Color |
|---|---|
| Pure Solid | Lustrous metallic gray |
| Pure Liquid | Black/violet |
| Pure Gas | Violet |
| Solution in Water | Light orange-brown |
This difference in color highlights how the physical state and the solvent can significantly alter the visual properties of a chemical compound. The specific light orange-brown color observed in aqueous iodine solutions is an important characteristic for its identification and use in laboratory settings and industrial applications.
