Determining the Theoretical Heat of Neutralization Using Hess' Law AH® for HCl(aq), NaOH(aq), H2O(l), and NaCl(aq) are -167.16, -470.11, -285.83, and -407.27 kJ/mol, respectively. Use Hess' law to calculate the heat of neutralization in kJ/mol. AHRx = H; (products) - H; (reactants) NaOH(aq) + HCl(aq) → HOH(1) + NaCl(aq) Heat of Formation -470.11 - 167.16 -407.27 kJ/mole Show all your calculations below. Your result will be considered as the "literature" value.

Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
