Homework Help: Heat of solution for sulfuric acid in water

  1. Jul 5, 2009 #1
    1. The problem statement, all variables and given/known data

    How can I calculate the enthalpy of solution for sulfuric acid at 30°C/68°F, for 0,2;0,5;1 mol/kg?

    2. Relevant equations



    3. The attempt at a solution
    I tried using a enthalpy-concentration diagram, but I cannot read it. I would apreciate if anyone could help me!

    what is this diagram you have? what data are you provided with?

    This one: http://docs.google.com/gview?a=v&q=cache:sexRAoFSlI4J:www.norfalco.com/documents/NorFalco_H2SO4Property07.pdf+calculate+enthalpy+sulfuric+acid&hl=en&gl=br [Broken]

    The only data I got is the concentration of the solution H2SO4 and water. I needed to find the theorical enthalpy of solution for this reaction, to compare with the results I got from the experiment.
