THe enthalpy of neutralization of HCN (aq) with NaOH (aq) is -12.0 kJ/mol. Using your value for the enthalpy of neutralization of H+(aq) with OH-(aq) and the technique used in question 2, determine the enthalpy of ionization of HCN. Compare the relative amounts of ionization of HCL and HC2H3O2. Which is the stronger acid? Question 2. The neutralization of HC2H3O2 (aq) by NaOH(aq) (part C) can be considered to be the sum of the neutralization of H+(aq) by OH-(aq) (part...

Experiment - Enthalpy of Neutralization Use Hess' Law to Calculate the enthalpy of dissociation for chloroacetic acid. H (aq) + OH -> H2O (l) ΔHn(HCl) HC2H2ClO2(aq) + OH (aq) -> C2H2ClO2 + H2O (l) ΔHn(HC2H2ClO2) We used a strong acid, HCl as the limiting reactant and NaOH as the the excess. Weak acid: HC2H2ClO2 (aq) + H (aq) + C2H2ClO2 (aq) ΔHd(HC2H2ClO2) HCl: Average ΔHn = -59 KJ HC2H2ClO2: Average ΔHn = -61 KJ
