Question

150. mL of 0.350 M HCI was mixed with 150. mL of 0.350 M NaOH in a calorimeter (of
negligible heat capacity). The initial temperature of the HCI and NaOH solutions was the
same, 23.25°C, and the final temperature of the mixed solution was 25.60°C. Calculate the
heat of neutralization for the reaction:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O)
dsol = 1.00 g/mL; S.H.sol = 4.184 J/g °C
