You would like to measure the heat of neutralization of an acid with a base. You mix 125 mL each of 0.75 M HCl and 0.75 M NaOH, both at a temperature of 23.8 °C in a calorimeter cup equilibrated to that same temperature. After following the temperature change for 10 minutes and extrapolating it back to the time of addition, you find that the "final temperature" after mixing was 28.4 °C. Previously you measured the heat capacity of the calorimeter cup (Ccup) to be 93 J/°C.

What is the change in enthalpy for the neutralization?


Write the net ionic equation for this neutralization reaction, including the states of matter (i.e. (aq)) for the reactants and products.
