Hello,

i need Heat of reaction of fluoboric acid for my final year project. It is produced form HF and Boric acid at 50 deg C.
Result product HBF4(Fluoboric acid ) and water.


i didn't find any relevant information in text books. and other web site source to find heat of reaction data and heat of formation.

Also i want to calculate enthalpy of product. What is the enthalpy reference point for HBF4 solution or HBF4 .
Similarly How can i calculate boric acid enthalpy ( which is availble at 25 deg C )


thanks
