Document Summary
Heat of neutralization with strong and weak wlectrolytes. The study of energy change is an important part of chemistry. Fundamental to the thermo-chemistry is the law of conservation of energy, which states that energy is neither created nor destroyed, but can be converted from one form to another. The enthalpy (h) of a substance, sometimes called its heat content, is an indication of its total energy content. In this experiment, the specific heat capacity of each solution will be assumed to equal to that of water, at 4. 184 j / (deg * g) (lab manual). Reactants can fall into two categories, strong and weak electrolytes. Strong electrolytes are substances that completely, or almost completely, ionize and dissociate in solution. Some examples include solutions of hcl, koh, naoh and kcl . Weak electrolytes, on the other hand, only partially dissociate into ions .
