What observational changes occur when iodine and hexane mix?
Accepted Answer
When iodine (I₂), a solid at room temperature, is added to hexane (C₆H₁₄), a nonpolar solvent, the following observational changes occur:
1. Dissolution: Iodine dissolves in hexane, forming a violet solution. This is due to the similar nonpolar nature of both iodine and hexane, allowing for strong intermolecular interactions.
2. Color Change: The initial purple-black solid iodine disappears as it dissolves in the hexane, resulting in a characteristic violet color of the solution.
