How to prepare fluoro boric acid from HF and boric acid?
A.
[hanson]
4 HF + H3BO3 --> HBF4 + 3 H2O
Simply add slowly an excess of Boric Acid to the
Hydrofluoric acid, until the Boric acid no longer
goes into solution. The solution will get hot to the
boil if you do it too fast. You will get a slight amount
of excess (~ 5-10%) Boric acid in the HBF4 this way.
If you need a more exact HBF4 then do it stochiometrically.
But for that you must post first the conc of the educts.
I am sure that some posters will give you the calcs.
Like other posters said: "Careful", it's very nasty *****!

ahahahaha... ahahaha... Thanks Donald, "as can be seen",
"it is easy to see" that your post must be cited for reposting:
---------------------------------
donald j haarmann's RESEARCH DEFINITIONS
---------------------------------
The following phrases, frequently found in technical writings,
are defined here for your edification and enlightenment. This
list was plagiarized from some unknown genius who evidently
had read one to many scientific papers.
IT HAS LONG BEEN KNOWN
- I haven't bothered to look up the original reference.
OF GREAT THEORETICAL AND PRACTICAL IMPORTANCE
- Interesting to me.
WHILE IT HAS NOT BEEN POSSIBLE TO PROVIDE DEFINITE
ANSWERS TO THESE QUESTIONS
- The experiments didn't work out, but I figured I could get a
paper out of it.
EXTREMELY HIGH PURITY, SUPER-PURITY
- Composition unknown except for the exaggerated claims
of the supplier.
THREE OF THE SAMPLES WERE CHOSEN FOR DETAILED STUDY
- The results on the others didn't make sense and were ignored.
ACCIDENTALLY CONTAMINATED DURING THE EXPERIMENT
- Accidentally dropped on floor.
HANDLED WITH EXTREME CARE DURING THE EXPERIMENTS
- Not dropped on floor.
TYPICAL RESULTS ARE SHOWN
- The best results are shown.
PRESUMABLY AT LONGER TIMES
- I didn't take the time to find out.
THESE RESULTS WILL BE REPORTED AT A LATER DATE
- I might get around to this problem sometime.
THE MOST RELIABLE VALUES ARE THOSE OF JONES
- He was a student of mine.
IT IS BELIEVED THAT
- I think.
IT IS GENERALLY BELIEVED THAT
- A couple of other guys think so too.
IT MIGHT BE ARGUED THAT
- I have such a good answer for this objection that I shall now raise it.
CORRECT WITHIN AN ORDER OF MAGNITUDE
- Wrong.
IT IS TO BE HOPED THAT THIS WORK WILL SIMULATE
FURTHER WORK IN THE FIELD
- This paper is not very good, but neither are any of the others
on this miserable subject.
THANKS ARE DUE TO JOE GLOTZ FOR ASSISTANCE
WITH THE EXPERIMENT AND TO JOHN DOE FOR VALUABLE
DISCUSSIONS
- Glotz did the work and Doe explained to me what it meant
PRELIMINARY EXPERIMENTS HAVE SHOWN.
- We did it once but couldn't repeat it.
THE W-Pb SYSTEM WAS CHOSEN AS BEING ESPECIALLY
SUITABLE TO SHOW THE PREDICTED BEHAVIOR.
- The fellow in the next lab already had some made up.
