Suppose you did the dissolution of NaCl(s) experiment again and found that for a 0.837 M solution of NaCl(aq) with a mass of 104.8 g, the temperature of the solution went from 23.23 °C to 22.90 °C (i.e. ΔT = -0.33 °C). Use the equations below to find ΔHdiss.

Based on the appearance of the pH vs titrant volume plot, the titrant is a(n) [ansA] and the analyte is a(n) [ansB].
