Enthalpy, represented by the now n (mol of naoh) is found plug this into equation a-3 also the enthalpy of neutralization (d h) calorimetry - experiment a. What is the enthalpy (heat) of neutralization neutralisation is the reaction between an acid and a base to form a salt and water some examples of neutralisation reaction are as follows. The heat of neutralization(better known as enthalpy of neutralization) is the energy released when one equivalent of acid reacts with one one equivalent of a base (neutralization reaction) to produce salt and water as the products.

How to calculate the temperature from heat of neutralisation up vote 1 down vote favorite the heat of neutralization of $\ce{hcl~ (aq)}$ by $\ce{naoh}$ is $\mathrm . Calorimetry and molar enthalpy the purpose of calorimetry is to use an instrument known as a calorimeter to determine the enthalpy of a substance undergoing chemical change. This amount of energy is released in the environment as heat during the neutralization, that is an exothermic reaction the amount of heat per mole of water . Understanding why enthalpy can be viewed as heat content in a constant pressure system.
