Enthalpy Experiment

Use Hess's law to determine the enthalpy change of the reaction between aqueous solution of ammonia and hydrochloric acid

Compare calculated enthalpy change with the experimental results



The experiment aim was to determine the enthalpy of the chemical reactions, and using Hess's law to verify the enthalpy of reaction between ammonia and chloric acid. We carried out a series of reactions in which we were able to determine the initial and final temperature. We used the variation of temperature and the mass each of solution to calculate the heat which was released or absorbed in the reaction using the formula.
