Summary/Conclusions: In this lab, our objective was to acquire measurements of calorimetry and use the data we gathered to determine reaction enthalpies using Hess’ Law. Calorimetry is the study of heat flow and depends upon specific heat, mass and change in temperature. Hess’s law states that the heat flow in a reaction that is the sum of the two other reactions is equal to

Unformatted text preview: the sum of the heat flows in those two reactions. We tested the validity of this law by measuring the heat of neutralization for aqueous solutions of a strong acid (HCl) and a strong base (NaOH), the heat of solution for dissolving the soft pellets of strong base (NaOH), and the heat of reaction for doing both simultaneously. Our calculations from the date collected came within 15% to the actual measured value....
