Performing calorimetry was important because although the process has been around for a long time, methods are always progressing and improving. Data and calculations made in the experiment allow the audience, as well as the experimenter to compare and contrast certain techniques and how that effects the results (Hermminger, W & Hoehne G., 1984).

Given. Lab 4: Calorimetry. In the calorimetry lab, the molar value of Δ Hsolution (in kJ/mol) for dissolving an ionic salt in water was determined. In a similar experiment, the mass and temperature of water in an enclosed styrofoam cup was measured. A weighed amount of solid NH 4 ClO 4 is mixed into the container.
