The most important aspect of the experimental technique in this experiment is?

NaOH(aq) + HCl(aq)  → NaCl(aq) + H₂O(l)  ∆H_A

NaOH(s) + HCl(aq)  → NaCl(aq) + H₂O(l)  ∆H_B

NaOH(s)   → NaOH(aq)  ∆H_C

What is the relationship between the enthalpy changes for the above reactions?

To calculate the heat absorbed by the calorimeter you:

In this experiment you will draw graphs of temperature vs. time showing how the solution temperatures vary before and after mixing. An example is shown below.

From which point on this graph should the temperature of the mixture be recorded?

The heat associated with the reaction which happens in the calorimeter is calculated by:

Calculate the amount of heat required to raise the temperature of 657.9 mL of a solution from 23.9 °C to 47.5 °C if the solution has a density of 1.04 g mL^–1 and a heat capacity of 4.08 J K^–1 g^–1.
