* Lewis Acid: FeBr3 acts as a Lewis acid. Lewis acids are electron pair acceptors. The iron (Fe) in FeBr3 has an empty d-orbital, making it capable of accepting electron pairs.

* Reaction with Water: When FeBr3 reacts with water, it forms HBr (hydrobromic acid), which is a strong acid. This reaction demonstrates its acidic nature:

FeBr3 + 3H2O → Fe(OH)3 + 3HBr
