Answer:
FeBr₃ and NaOH
Step-by-step explanation:
In a double displacement reaction, the ionic species of both reactants are exchanged between each other, as follows:
- Fe(OH)₃ + 3NaBr → FeBr₃ + 3NaOH
That way the cation Fe⁺³ (originally bonded to OH⁻) is bonded to the anion Br⁻ instead, while Na⁺ bonds to OH⁻ (instead of Br⁻).
