Investigation into temperature change during neutralisation.

Introduction. The following is an experiment into temperature change in an exothermic reaction taking place between Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) and also how the concentration of the acid will vary these results. The characteristics of the reaction feature a neutralisation, an energy change (shown as a temperature change) that is usually exothermic (gives out heat). The reaction of neutralisation is exothermic because of the bonds being broken and made in the reaction. …

…experiment. My method worked extremely well, and I feel it is the best possible method to use in further experiments. But if needs be to change the experiment in some way, perhaps difference in the concentration of the alkali instead of the acid, may alter the results in someway. Even the use of either more controlled conditions or different insulation is something to look into. Choosing another variable to control is also a feasible option.
