Document Summary
The purpose of this experiment was to measure heats of several reactions and also the enthalpies of neutralization of a strong and a weak acid. To perform the experiment, the system must be effectively insulated from its surroundings. Using a styrofoam cup, an effective and a suitable calorimeter was made which served as the reaction vessel. The temperature change from a reaction carried out inside the calorimeter can be measured and the change in heat content may be calculated if the total heat capacity of the system (calorimeter and contents) is known. In general, the heat q in joules can be expressed as where v is the volume in ml, is its density in g/ml, is the specific heat capacity in j/gk, and (= tfinal (1) Tinitial) is the change in temperature in k. In the first part of the experiment, the specific heat capacity of the calorimeter is measured and calculated using the formula:
