Heat of Neutralization 22.0c Original temp of HCl solution Original temp of NaOH solution 22.60 Final temp of neutralized mixture 35.30 Change in temp (use average original temp of 26.6C HCl and NaOH) U QH20 for the reaction (get mass using 50.0 ml solution and d= 1.02 g/mL) AH for the reaction (egn 4) J AH per mole kJ/mol
Preaction = AHreaction = -9H20 (eqn 4) Datum NaOH (s) - Na+ (aq) + OH-(aq); AH = AHsolution (eqn 5) Solution with OH in in H(aq) + OH(aq) - HO (1): AH = AH neutralization (eqn 6)
