Another thing I was thinking: don't I have to take into account the fact that HF can also form H2F- and H2F2 ?

Thank you for this answer ! that helps a lot. Just one more question : how do you know that it is this reaction that is going to take place ? did you find it in a book ? did you guess it ? did you deduce it from something ? thank you for your help

I am aware of the risks and I use safety equipment... but yes it's dangerous !

Hi, I am currently working on the chemical etching of zirconium oxide (ZrO2), but chemistry is not my specialty so a little bit of help would be really welcome =) The experiment is quite simple : I put a ZrO2 sample in a hydrofluoric acid solution (48% wt) for different times at room temperature, and I study the effect on the surface of the sample. My aim right now: knowing (theoretically) what are the reactions that can take place, what are the products that actually appear and (maybe the most important) what mass of ZrO2(s) can be dissolved in the solution My questions : what is the methodology I should follow ? Which kind of diagram should I calculate ? and is there some freeware that can help me for this kind fo work ? Thank you for your help !
