explain it
In chemistry, thermochemistry is an important branch of chemistry, which is used to cope with thermal energy changes that are related to chemical reactions. As we know, when salts are dissolved in water, there are two significant contributions to the heat energy changes. In the first process, there are electrostatic attractions between ions of opposite, which is related to the lattice enthalpy that is the amount energy required to separate one mole of an ionic compound into its constituent gaseous ions. The second process is called the hydration enthalpy, both of the processes result to the energy changes when salts are dissolved in the water. In this experiment, the purpose is that lets students can be proficient in the use of a digital data recorder and digital temperature probe and volume measurements, additionally, making them learn present experimental data in graphical format and apply calculations to quantify a change in enthalpy
