EXPERIMENT: HEAT OF NEUTRALIZATION 48 OBJECTIVE A computer using a LoggerPro program and an attached thermocouple probe will be used to measure the temperature changes accompanying neutralization reactions. The temperature change will be used to calculate the enthalpy change. The enthalpy change accompanying each reaction will be used to determine the enthalpy change of a theoretical reaction using the Law of Heat Summation THEORY The Heat of Neutralization for a particular acid-base reaction can be determined by measuring the energy change as a function of heat flow. Heat of the system (qsys) =- Heat of the Surroundings (qsurr) (1) Neutralization reactions are exothermic. The energy released by the neutralization reaction is equal to the sum of energies gained by the product solution and the container holding the reactant solution (calorimeter). Thus, the individual system, surrounding components are defined as: Heat released by reaction (q) =-[Heat gained by calorimeter(qcal) + Heat gained by solution(qsoln
