A few drops of HCl are added to a tube containing the sodium salt of 2,6-dichloroindophenol (pure color), 4 mL of water and 2 mL of methylene chloride. After shaking, the methylene chloride layer is now pink and the aqueous layer is clear. In which layer is the compound dissolved? Using solubility principles and the polarities of the two solvents, explain why the compound is dissolved in this solvent?
