What is the heat of formation value for AQUEOUS phosphoric acid (H3PO4)? I can only find it for liquid. thank you

    The problem is the heat of solution, which affects measurements. So technically, the heat of formation of the acid in solution is the same as liquid, but if you are measuring or calculating heats, you have to add in the heat of solution to the equation.
