what is the product of HF(g) and BF3 (g)?

Question

HF(g) + BF3 (g) ---> ????????????

is it no reaction

Answer 1

humm ... I know Boron trifluoride is a colorless gas that hydrolizes in water to form boric acid and hydrofluoric acid

BF3(g) + 3H2O(l) yields H3BO3(s) + 3HF(g)

then..

BF3 + HF yields H+ + BF4 -

which is fluoric acid HBF4

Answer 2

I don't think these react; the only possibility would be a reaction of the type:

3 HF + BF3 ---> BH3 + 3 F2

This reaction is definately not going happen as written; it involves taking away electrons from fluorine. In fact, the reverse of this reaction (equilibrium far to the left) is the one which would be most favorable.

Note: charged species might be stable in solution, but probably not in the gas phase.
