Can we prepare boric acid from BF3 ?

Expert Answer:

Boron trifluoride reacts with water to give boric acid and fluoroboric acid. The reaction commences with the formation of the aquo adduct, H2O-BF3, which then loses HF that gives fluoboric acid with boron trifluoride

4 BF3 + 3 H2O → 3 HBF4 + B(OH)3
