Question

The neutralization reaction of HClO4 (strong acid) with NaOH is given below.

HClO4 (aq)  + NaOH (aq) →  H2O (l)  +  NaClO4 (aq)             ΔH = ?

128.1 ml of 0.649 M HClO4 is combined with 128.1 ml of 0.649 M NaOH in a perfect calorimeter.  Both of the starting solutions were initially at a temperature of 34.73 °C.  After the reaction is complete the final temperature of the solution in the calorimeter is 39.16.  (You may assume that the specific heats of all solutions are the same as that of pure water and that the denisty of each solution is 1.00 g/ml.)

 

Calculate the enthalpy of neutralization (ΔH) for the reaction shown above (in kJ).
