12 ENTHALPY OF NEUTRALIZATION DATA ANALYSIS (Fill out and submit to the Heat of Neutralization folder by the due date) Hess's Law Analysis. 6. Indirect determination of AH Procedure Part: Write the "Reactions, in the spaces below, including physical states Your calculated AH, kJ/mol Part A Dissolving NaOH(s) Part B Neutralizing HCl(aq) with NaOH(aq) CANCEL and ADD the two equations and their AH's 7. Direct determination of AH: Procedure Part: Write the reaction in the space below, including physical states Your calculated AH, kJ/mol Part C Neutralizing HCl(aq) and NaOH(s) 8. Compare the AH values obtained from the indirect determination to the direct determination. How far apart are your two values (numerically)? How close (or far away) were the values from the summation of enthalpy (after cancelling and adding) and the directly measured enthalpy (#7)? What experimental errors might have contributed to the difference if you were off by more than 10 kJ?
