What is going on in the hexane layer at the end of a Group I Anion experiment?On a qualitative Analysis for Anions experiment, to a sample, I had to add 3 M HNO3 until it was just acidic. Then, I had to add 3 drops of NaOCl solution then 1mL hexane. After shaking it well, if the solution was yellow, the anion was Br-. If the solution was brown or purple, it was a I- Anion. What is going on with the hexane layer? What does it have to do with the periodic table?

What is going on in the hexane layer at the end of a Group I Anion experiment?

On a qualitative Analysis for Anions experiment, to a sample, I had to add 3 M HNO3 until it was just acidic. Then, I had to add 3 drops of NaOCl solution then 1mL hexane. After shaking it well, if the solution was yellow, the anion was Br-. If the solution was brown or purple, it was a I- Anion. What is going on with the hexane layer? What does it have to do with the periodic table?
