In this practice, it is possible to measure the heat released by a neutralization reaction and to find its enthalpy. It is necessary to balance the energy of the acid and the base to an equilibrium point. To do so, the simulator recreates a laboratory with a calorimeter, a heating plate, a universal support, thermometers, a flask with an acid and a flask with a base (sodium hydroxide) as well as other materials and supplies to complete this practice.
