HF + HNO3 in mannitol
« on: January 26, 2020, 10:26:02 AM »
Hello,
I have a question about fixing the equation of a reaction i made in class :

I made a chemical dosage of a mixed solution of HF + HNO3 by NaOH in Mannitol, but i don't know if my equation is right i found this :


HNO3 + NaOH = NaNO3 + H2O
HF + NaOH = NaF + H2O

So it gives me :

HNO3+HF+2NaOH = NaNO3 + NaF + 2H2O

How can i find the concentration of HNO3 and HF please ? Is my equation right ?

Thanks you in advance

Only with titration with NaOH no way. You need an additional method to determine fluoride.

I made the titration with NaOH + EtOH as a ph-metric , it is possible to determinate it ?

No you have a mixture of two acids. How you want to determine HNO3 and HF.
You can titrate the mixture and with a second method for fluoride you can do substraction to get nitric.

Besides the question about dosage, how potentially dangerous is it to mix mannitol and nitric acid plus an other acid?
