Here's why:
* Iodine (I2) is a nonpolar molecule.
* Tetrachloromethane (CCl4) is also a nonpolar solvent.
* Like dissolves like: Nonpolar substances dissolve well in nonpolar solvents due to similar intermolecular forces.
This solution is often used in spectroscopic analysis because:
* Iodine's color in CCl4 is very distinct. This allows for easy visual identification and quantitative analysis.
* CCl4 is transparent to visible light. This allows for accurate measurement of the light absorbed by iodine.
Important Note: Tetrachloromethane is a toxic and carcinogenic compound. It should be handled with extreme caution and used in well-ventilated areas.
